Flood the flask what an invention. Radio "Chemistry is interesting." Naboyka in Kie

Chemist Day - professional holiday Chemical industry workers - celebrated on the last Sunday of May in Russia, Belarus, Kazakhstan, Uzbekistan and Ukraine. In 2014, the holiday falls on May 25th.

AiF.Ru talks about unusual facts from the life of chemists and chance that led to great discoveries.

An inappropriate discovery

In 1903. french Chemist Edward Benedirtus Inadvertently dropped the flask filled with nitrocellulose. Glass cracked, but did not scattered on small pieces.

Benedictus applied the opening in the production of windshield for cars. It was a "sandwich", made of nitrocellulose leaf between two layers of glass. Of course, the glass with a strong blow still broken, but the fragments remained to stay on the sheet of nitrocellulose, instead of flying in the face of passengers of the car during an accident.

Glowing professor

Academician Semen Wolfkovich, Professor of Moscow University, conducted experiments with phosphorus. Gaseous phosphorus during the work soaked the clothing of the scientist. Therefore, when Wolfkovich returned home on the dark streets, his clothes radiated a bluish glow, and from under the shoes flew sparks. Every time he was going to the crowd, who took a scientist for the otherworldly creature, which led to the spread of rumors about the "luminous monk" in Moscow.

From physics in chemists

"Father" nuclear Physics Ernest Rutherford Once he stated that "all sciences can be divided into two groups - to physics and collecting brands." However, the Nobel Prize was awarded to him in chemistry "For the studies held in the field of decay of elements in the chemistry of radioactive substances" (1908). Subsequently, Rutherford noticed that from all the transformations that he managed to observe, "the most unexpected has become its own transformation from physics in a chemist."

Opening antibiotics

Antibiotics were open by chance. Scottish bacteriologist Alexander Fleming did not really like to remove his laboratory table, which, by a lucky accident, helped him in 1928 to make one of the most important discoveries XX century in medicine.

Unlike its neat colleagues, cleared cups with bacteria immediately after the end of working with them, Fleming was not soap cups for 2-3 weeks until its laboratory table turned out to be cluttered. Then he was taken for cleaning, I looked through the cups one after another, so as not to miss anything interesting. In one of the ass, he discovered the mold, which, to his surprise, was oppressed by a sinking bacterium. So the first antibiotic was opened - Penicillin.

In addition to the treatment of patients, Flemming used his discovery in painting. His paintings were written by non-oil or watercolor, but multicolored strains of microbes.

Rubber inventor

American Charles Chudjir Accidentally opened the recipe for rubber manufacture. He mistakenly heated a mixture of rubber and sulfur on the kitchen stove (according to another version, left the substance in the furnace). So vulcanization was opened, in the process of which rubber becomes rubber.

Herman himself allowed that the process of vulcanization was not open as a result of the use of a classic scientific method, but the inventor argued that it was not and accident. Rather, the result of experimental activities and observations.

Unknown Mendeleev

Famous Russian scientist Dmitry Mendeleev He was a seventeenth child in the family. In school, he learned poorly and once even remained for the second year. In the first year of the institute, he managed in all subjects, besides mathematics, get unsatisfactory marks. Yes, and in mathematics, he had only "satisfactory" ... But on the senior courses, the case went differently. Mendeleev graduated from the Institute in 1855 with the Gold Medal. Mendeleev loved to twist the books, glue the frames for portraits, as well as make suitcases. In St. Petersburg and in Moscow, he knew him as the best in Russia of the masters of the master. "From Mendeleev," the merchants said. Miscellaneous Scientist Periodic Table chemical elements, by legend, dreamed of him in a dream. However, the scientist himself said: « I'm over her, maybe, twenty years thought, and you think: sat and suddenly ... ready ".

Difference difficulties

Sugar substitute - Sukraloza - was opened by chance. Professor Leslie Hugh gave an indication who worked with him foreign student Test (eng. Test) obtained in the laboratory chlorinated sugar compounds. The student talked well in English and decided that he was asked to try the substance for the taste (English Taste). He found the connection exclusively sweet.

Hazing inventor

English scientist joseph attractedin 1767, it became interested in the nature of bubbles, which go to the surface in the fermentation of beer. Over the beer chhan, he placed a bowl with water, which then tried to taste and discovered that it had a refreshing effect.

Priestley discovered nothing but carbon dioxide, which is used today in the manufacture of carbonated drinks. After five years, the scientist has published a job in which a more perfect method for producing carbon dioxide by the reaction of sulfuric acid with chalk was described.

Great chemical

In one day of 1837, a deafening explosion rang out in the basement of the private boarding house in Kazan. It turned out that one of the pupils of the institution, Sasha Butlers, secretly equipped the laboratory in the basement, where he conducted chemical experiments.

The Pedagogical Council decided to expose "Hooligan" on the mixture, and he was bred in the dining room with a ski-hanging on his chest, on which large letters were written: "Great Chemist."

Inventing this mockery inscription, the unlucky teachers of Sasha were not allowed, of course, and the thoughts that she would be a prophetic and that the "violater of the board rules" began to be a truly great chemist - Alexander Mikhailovich Butlerov.

As imperfect knowledge of English language Helped to open one of the sugar substitutes?

One of the most effective sugar substitutes - Sukraloza - was opened by chance. Professor Leslie Hugh from the Royal College in London gave an indication to the student who worked with him Shashikant Phandnis to experience (in English "Test") the substance of trichlorosacham obtained in the laboratory. The student knew English for a far from perfect level and instead of "Test" heard "Taste", immediately trying the substance to taste and finding it very sweet.

What part of the car was invented by chance?

Unbreakable glass was invented by chance. In 1903, French Chemist Edward Benedirtus accidentally dropped the flask filled with nitrocellulose. Glass cracked, but did not scattered on small pieces. Realizing what is the matter, Benedictus made the first winding windows of a modern type to reduce the number of victims of automotive accidents.

Who was the person called Muscovites in the legends with a luminous monk?

Academician Semen Wolfkovich was among the first Soviet chemists who had experienced with phosphorus. Then the necessary precautions have not yet been accepted, and the phosphorus gaseous during the work has soaked clothing. When Wolfkovich returned home around the dark streets, his clothes radiated a bluish glow, and sparks were evicted from under the shoe. Every time he was going to the crowd and accepted a scientist for the otherworldly creature, which led to the dissemination of rumors about the "luminous monk" in Moscow.

How did Mendeleev opened a periodic law?

The legend is widespread that the thought of periodic table Chemical elements came to Mendeleev in a dream. Once he was asked if it was so that a scientist answered: "I thought about it, maybe twenty years old, and you think: I sat and suddenly ... ready."

What famous physics was awarded the Nobel Prize in the field of chemistry?

Ernest Rutherford was engaged in research mainly in physics and once stated that "all sciences can be divided into two groups to physics and collecting brands." However, the Nobel Prize was presented to him in chemistry, which became a surprise both for him and for other scientists. Subsequently, he noticed that from all the transformations that he managed to observe, "the most unexpected was the own transformation of physics into a chemist."

What birds helped mines?

Canaries are very sensitive to the content of methane in the air. This feature was used at the time of mines, which, descending underground, took a cage with a canary. If the singing has not been heard for a long time, it means it should be rising upstairs as quickly as possible.

How was the vulcanization?

American Charles Chudjir accidentally opened a recipe for rubber manufacturing, which does not soften in the heat and does not become fragile in the cold. He mistakenly heated a mixture of rubber and sulfur on the kitchen stove (according to another version, left a sample of rubber from the furnace). This process was called vulcanization.

What creatures are guilty of bloody waterfall color in Antarctica?

In Antarctica, bloody waterfall comes out of the Taylor glacier. Water in it contains a bivalent iron, which, connecting with atmospheric air, is oxidized and forms rust. This gives a bloody-red waterfall. However, the divalent iron in water occurs is not just like that - it is produced by bacteria living in the reservoir in the external world deeply under the ice. These bacteria managed to organize a life cycle with the complete absence of sunlight and oxygen. They process the residues of the organicists, and "breathe" with a triumphant iron from surrounding rocks.

Triplex - multilayer glass (two or more organic or silicate glass, glued together with a special polymer film or a photographic composition, capable of holding fragments when hit). As a rule, it is manufactured by pressing when heated.

History of creation

The tribe invention has helped the case.
1903 year. The French chemist Edward Benedictus when preparing for experiments accidentally dropped on the floor of the laboratory glass flask. And surprise was waiting for him - although the flask was crashed, but she kept the original shape, the fragments joined some film. Before this flask was used for experiments with cellulose nitrate (nitrocellulose) - alcohol solution of liquid plastic - and just forgot to wash. Plastic is dried by a thin and transparent layer, which kept the fragments of the broken flask.
Benedict locked in the laboratory for a day. He came out from there with the first triplex - he combined two glasses with a layer of nitrocellulose.
"I suppose my invention has great potential for future use," the Frenchman wrote in his own diary. The French scientist was not mistaken.

Application triplex

First new Material Found an application in the army. During the First World War from Triplex, glasses were made for gas masks.
And in 1927, Henry Ford ordered to equip all its cars with safe glasses.
Today triplex apply:

1. In the transport industry. With glazing glass cars, airplanes, ships, railway rolling stock.

2. When booking. Triplex applies to armored cars and when booking glass buildings. Such glasses are kept as physical impact (scrap, hammer, sledgehammer), and firearms. For example, the seven-layer triplex glass "stops" a bullet, powdered from the Kalashnikov machine.

3. In construction. Here the scope of use is the most extensive - from the facades of buildings to stairs and partitions.

Production and characteristics of triplex

Production Consider on the example of the plant of the company "Pokrokoy" - http://stekko.ru/materialy/triplex/

In short, the technology is such - two blanks - glass sheets (the type of glass is selected based on the technical design) glued together with a special film. The process takes place in a vacuum chamber at a temperature of 130 -140 degrees Celsius.

Main characteristics:
- Resistance to wear, shocks and damage. The glass maintains the load to 200-300 kg per 1 m2;
- safety. Even if the glass breaks, the fragments will hold the film;
- glass thickness from 6 to 40 mm, of any color and shape;

Triplex of the company "Stroke" is high quality, stylish and safe!

In conclusion, I propose to view the triplex security check.

It happens that scientists spend years and even a decade in order to present the world a new discovery. However, it also happens differently - inventions appear unexpectedly, as a result of unsuccessful experience or a simple accident. It is difficult to believe, but many devices and drugs that have changed the world were invented quite by chance.
I propose the most famous of such accidents.

In 1928, he noted that one of the plastic plates with the pathogenic bacteria staphylococcus in his laboratory was covered with mold. Nevertheless, Fleming left the laboratory for the weekend, never washing the dirty dishes. After the weekend, he returned to his experiment. He studied a plate under the microscope and found that mold destroyed bacteria. This mold turned out to be the main form of Penicillin. This discovery is considered one of the greatest in the history of medicine. The value of the opening of a Fleming has become clear only in 1940, when mass studies have begun a new type of antibiotic drugs. Thanks to this random discovery, millions of lives were saved.

Safety glass
Unbreakable glass is widely used in the automotive industry and construction. Today it is everywhere, but when the French scientist (as well as the artist, composer and writer), Edward Benedirtus in 1903 accidentally dropped an empty glass flask on the floor and she did not crash that he was very surprised. As it turned out, before that, a collate solution was kept in the flask, the solution was evaporated, but the vessel walls were covered with a thin layer.
At that time, the automotive industry was intensively developed in France, and the windshield was made from ordinary glass, which was the cause of many driver injuries, for which Benedictus drew attention. He saw real benefits to rescue human lives in using his invention in cars, but the automakers considered it too expensive for production. And only years later, when during World War II Triplex (such a name received new glass) was used as glass for gas masks, in 1944 Volvo applied it in cars.

Pacemaker
The pacemaker, which now saves thousands of lives, was invented by mistake. Engineer Wilson Greitbatch worked on creating a device that should have recorded heart rhythm.
Once he inserted an inappropriate transistor into the device and found that there were oscillations in the electrical circuit, which are similar to the right rhythm of the human heart. Soon the scientist created the first implantable pacemaker - a device that serves artificial pulses for the heart of the heart.

Radioactivity
Radioactivity was open randomly by Henry Becquarel scientist (Henri Becquerel).
It was in 186, when Becquer worked on the study of phosphorescence of uranium salts and recently open X-rays. He conducted a series of experiments in order to determine whether fluoric minerals can produce radiation when contact with sunlight. The scientist faced a problem - the experiment was carried out in winter when the bright sunlight was lacked. He wrapped uranium and photoflax in one package and began to wait for a sunny day. Returning to work, Becquille discovered that Uranus was imprinted on a photoplastic without sunlight. In the future, he, together with Maria and Pierre Curie, opened what is now known as radioactivity, for which, together with a memorial couple, he later received the Nobel Prize.

Microwave
Microwave, she is the "oven for heating popcorn," was born precisely thanks to a happy coincidence. And it all started - who would have thought! - From the project to develop weapons.
Percy Lebaron Spencer - self-taught engineer - was engaged in developing radar technologies in one of the largest companies in the world military-industrial complex Raytheon. In 1945, shortly before the end of World War II, he conducted research on improving the quality of radar. During one of the experiments, Spencer discovered that the chocolate bar who was in his pocket melted. Contrary to common sense, Spencer immediately dropped the idea that chocolate could melt under the influence of the body of the body - as a true scientist, he grabbed the hypothesis that the invisible radiation of Magnetron was "influenced" into chocolate.
Any sensible man immediately stopped and realized that the "magic" thermal rays took place in several centimeters from his dignity. Will be near the military, they would surely found a worthy use of this "melting rays." But Spencer thought about the friend - he was delighted with his discovery and considered it a real scientific breakthrough.
After a series of experiments, the first microwave weighing of about 350 kg with water-cooled was created. It was supposed to be used in restaurants, airplanes and ships - i.e. Where it was necessary to quickly warm up food.

Vulcanized tires
Do you hardly shock the news that rubber for automotive tires Invented Charles Gudir - he became the first inventor whose name was the final product.
It was not easy to invent rubber capable of withstanding the race for the maximum acceleration and car racing, which were all from the date of creation of the first car. And in general, Gudira had every reason to spread apart from the crystal dream of youth forever - he went to prison, he lost all his friends and almost drowned his own children's famine, trying to invent more solid rubber (for him it turned almost in an obsession ).
So, it was in the middle of the 1830s. After two years of unsuccessful attempts to optimize and strengthen the usual rubber (mixing rubber with Magnesia and Lime), Gudir and his family were forced to look for refuge on an abandoned factory and fish for food. Then the Gudir and made a sensational discovery: he mixed rubber with gray and got a new rubber! The first 150 rubber bags were sold to the government and ...
Oh yes. Rubber turned out to be poor quality and completely useless. The new technology turned out to be ineffective. Gudir was ruined - at once!
Finally, in 1839 Gudir wandered into a universal store with another portion of failed rubber. The people who gathered in the store were watched by the crazy inventor. Then they started laughing. In Riode, Gudir threw rubber lump on a hot plate.
Carefully having studied the burnt residues of rubber, Gudir realized that the only accidentally - invented the method of producing reliable, elastic, waterproof rubber. So from the fire was born a whole empire.

Champagne
Many people know that the champagne came up with the house of Pierre Perignon, but this monk of the Order of St. Benedict, who lived in the 17th century, did not intend to make wine with bubbles, and quite the opposite - he spent years, trying to prevent it, because hip wine was considered a faithful sign low-quality winemaking.
Initially, Perignon wanted to please the tastes of the French yard and create the appropriate white wine. Since the champagne was easier to grow dark grapes, he came up with a way of obtaining light juice from it. But since the climate in champagne is relatively cold, the wine should have wandered for two seasons, spending the second year already in the bottle. As a result, wine was obtained filled with bubbles of carbon dioxide, from which Perignon tried to get rid of, but unsuccessfully. Fortunately, the new wine very much liked the aristocracy of both French and English yards.

Plastic
In 1907, Shellac was used for isolation in the electronics industry. The cost of importing shellac, which was made from Asian beetles, were huge, so Chemik Leo Hendrik Baekeland decided that it would be nice to invent the alternative to Shellac. As a result of experiments, it received a plastic material that was not destroyed at high temperatures. The scientist thought that the material invented them could be used in the production of phonographs, however, it soon became clear that the material could be used much wider than it was supposed. Today, plastic is used in all spheres industry.

Saccharin
Sakharin, known to all slimming sugar substitute, was invented due to the fact that Konstantin Faliberg did not have a useful habit of washing his hands before meals.
It was in 1879, when Falberg worked on new ways of using a coal tar. Having finished his work day, the scientist came home and sat down to dinner. The food seemed to him sweetish, and the chemist asked his wife, why she added sugar to food. However, his wife did not seem sweet to his wife. Falberg realized that it was not really a sweet food, but his hands, which he didn't hear before dinner. The next day, the scientist returned to work, continued to study, and then patented a way to obtain an artificial low-calorie sweetener and began its production.

Teflon
Teflon, who facilitated the life of housewives around the world, was also invented by chance. A chemist from DuPont Roy Plankett studied the properties of Freon and for one of the experiments frozen tetrafluoroethylene gaseous. After freezing, the scientist opened the container and found that gas was gone! Plankett shook the canister and looked into her - there he discovered a white powder. Fortunately for those who at least once in their life did an omelet, the scientist became interested in the powder and continued his study. As a result, the same Teflon was invented, without which it is impossible to imagine modern cuisine.

Wafer horn for ice cream
This story may serve as an ideal example of a random invention and a random meeting that has incredited. And she is tasty enough.
Until 1904, the ice cream was served on sauces, and only at the World Fair of the Year, held in St. Louis, Missouri, two, it would seem that not related foods were inextricably linked.
On this particular roasting and stuffy World Fair of 1904, at a tent selling ice cream, things went so well that everything quickly ended the saucers. At the tent, located next door, and the selling challenge - subtle waffles from Persia, did not go, and its owner came up with the waffle in the cone, and on top to put ice cream. So I was born ice cream in a waffle horn, and in the near future it is not going to die, it seems.

Synthetic dyes
It sounds strange, but this is a fact - synthetic paint was invented as a result of attempts to invent a medicine from malaria.
In 1856, Chemik William Perkin (William Perkin), worked on the creation of artificial quinine for the treatment of malaria. He did not invent a new medicine from malaria, but he got a thick dark mass. Looking at this mass, Perkin discovered that she gives a very beautiful color. So he invented the first chemical dye.
His dye turned out to be much better than any natural dye: first, her color was much brighter, secondly, she did not burn out and was not washed away. The opening of Perkin turned chemistry into a very profitable science.

Potato chips
In 1853, in the restaurant of Saratoga, New York, a particularly capricious client (Railway magnate Cornelius Vanderbilt) constantly refused to eat potatoes FRI, which he was served, complaining that he was too fat and wet. After he abandoned several plates, the chef of the restaurant George Kram decided to take revenge on him and crashed in oil a little thin like a wafer of potatoes slices, and filed them to the client.
First, Vanderbilt began to say that this last attempt was too thin, and it is impossible to put it on the plug, but, having tried a few pieces, he remained very satisfied, and all visitors to the restaurant wanted the same thing. As a result, a new dish appeared on the menu: "Saratoga Chips", which was soon sold worldwide.

POST-IT stickers
The modest post-it stickers appeared as a result of accidental cooperation of the mediocre scientist and irritated parishioner of the church. In 1970, Spencer Silver, researcher of a large American corporation 3m, worked on the formula of strong glue, but was able to create only very weak glue, which could be removed almost without effort. He tried to promote his invention in the corporation, but no one paid attention to him.
Four years later, Arthur Fry, an employee of 3m and a member of the church choir, was very annoyed by the fact that the papers he put in his book by hymns as bookmarks constantly dropped out when the book was opened. During one service, he remembered about the invention of Silver Spencer, and experienced an epiphany (perhaps the church is the most suitable place for this), and then inflicted a little weak, but not damaging paper, Spencer glue to its bookmarks. It turned out that small sticky marks make just what they needed, and he sold this idea 3m. The trial promotion of a new product began in 1977, and today it is already difficult to imagine life without these stickers.
