Michelle Eugene Chevrel Biography

Years: Country: France has been preparing for a significant anniversary for three months now. His studies of the composition of fats led to the correct understanding of the process of sample. Chevrel devoted most of his scientific papers to the study of colors, coloring and studying the psychological and aesthetic effects of various combinations of colors on humans.

The successes of the Chevel in science did not only a French scientist. His scientific activity was widely known outside France, and the entire scientific world of that time was proud of the openings of the Chevrel. As a sign of our deep respect and appreciation, the scientist before the Museum of Natural History decided to establish his bust. Every day, the organizational committee of the exhibition received industrial goods obtained according to the methods of Shevell.

There were so many exhibits that it was completely impossible to expose them all in the windows. The end of August was approaching. The agricultural society also honored the scientist. On the occasion of the celebration, the large hall was festively decorated. At exactly two in the afternoon, the lackeys opened the front doors, and Chevrel majestically entered the hall.

In the depths of the hall, eleven people - chairmen of sections and each kept on a huge bouquet of roses: white, yellow, orange, pink, red, its perennial studies of colors, their combinations and perceptions are now symbolically expressed in these fragrant colors. How sincere their love for the scientist who gave his life to science! According to tradition, the chairman of the agricultural society was elected the oldest in age.

In the morning, people began to gather in the square of the museum. The marble stairs of the museum were stained with carpet paths strewn with fresh flowers. The walls of the building were draped by a wide variety of fabrics that were produced according to the Shevell method on tapestries. Delegations of scientific societies from all over France, as well as scientists from Europe, were only about two thousand people, gathered at the celebration.

The jubilant cries and songs of the thousands of crowds did not silent for a long time in the square. Chevrel almost did not listen to the speaker. How long it was, but it seems that only yesterday he still ran through meadows in violent games with his friends - boys from the central school of Anger. Madam Chevrel - in the girlishness of the ethyette Madeleine Bashel - was a large well -built woman.

He was always a favorite of teachers, as he knew a lot and studied a lot. The desire for knowledge led the seventeen -year -old Shevell to Paris. The lectures of Professor Furkroka were very interesting, but the main one for the young student was work in the laboratory. It was enough to conduct experience to directly observe them. Experiments, experiments, experiments need to work a lot, a lot, but you have done everything in a neat manner.

The Chevrel, embarrassedly lowered his head. They were found in the summer during an expedition in the valleys of exchange and Loires. You must analyze these bones. The Chevrel put the box on the table where he usually worked, and began to prepare the dishes necessary for analyzes: it was necessary to complete an interesting task. Ten thousand years ago, this gigantic animal wandered around our land.

And now the bone of the dinosaur should shed light on many not yet studied problems. Chevrel worked with enthusiasm. In the same year, Volen and Chevrel began to analyze human hair. Joint work brought scientists closer, they later became big friends, despite the age difference. The rest is only formality. I recently spoke with Professor Furcrois. You will work next to us. This will benefit science.

For us now the main problem is Indigo. Until now, you have not been engaged in it, so I want to familiarize you with something. There is a bluish-black powder in that flask. This is indigo. If it is heated, red pairs appear. Chevrel began to study indigo. The scientist was thoroughly cleaned, eliminated impurities in which purple paint may remain. It is difficult to answer this question now.

The analysis gives exactly the same results for both blue and red indigo. Here, look. The material, of course, is purple-red. Are there any errors in the analyzes? Later, as a result of the research work of a number of scientists, it was found that the blue and red indigo were only two isomeric forms of the same substance. In addition to the separation of two types of indigo, he managed to clarify the conditions under which they turned into a colorless, soluble compound in water.

Chevrel called the colorless compound of Leak-Indigo. Received red and blue shades of good quality. The question arose, are there any of these dyes of such indigo? Chevrel with enthusiasm began new research. First of all, these substances had to be extracted from crushed wood. The results showed that these are other, different from indigo dyes. Only this made it possible to firmly fix the dye on the fiber.

The letter attached to the sample said: “This soap was used to manufacture the water mixtures in our textile factory. We ask you to make its full analysis to determine the components.The Chevrel for a long time held a letter in his hands, reflecting on a new problem. To explore the soap, to establish a way to obtain it, but for this it is apparently necessary to explore the original fats of another natural product.

Plant fats and oils, animal fats are so different in appearance, properties, the composition makes sense to take on new problems? Chevrel continued his research on Brazplin and hematoxilin. In parallel with this, he was engaged in analyzes of the applied soap. The scientist dissolved some of its amounts in water, but the solution turned out to be heterogeneous, and small scales with pearl shine swam on the surface.

It is necessary to divide them and study each separately, ”Chevrel decided. It dissolves in alcohol, while fats are insoluble in it. In the year, Shelele managed to decompose fats and get a sweet substance that differs from sugars in its properties. I remember that he called this substance glycerin, however, there are enough memories, it's time to start work. In a short time, Sheverev was able to get fatty acid contained in shiny scales in its pure form.

In fact, the “margarine” acid obtained by the chevere was a mixture of palmithic and stearic acids. Research more and more fascinated the scientist. After processing their aqueous solutions with hydrochloric acid, it received several in the properties of fatty acids. Yun called the acid made from soap welded on seal fat; From soap, welded on sheep's sala, he secreted gyrhrician acid.

He later discovered the same most acid in the goat of the sala and established that it is a mixture of two acids - nylon and capricin. The number of fatty acids studied increased every day. What are fats? How are fatty acids connected in them? .. In the same year, he became a professor at the Chemistry Department in the Lyceum "Karl the Great". The separation and complete purification of fatty acids was particularly difficult for the cheval.

But separating stearinic acid from Margarinova was almost impossible. They were the subject of his pride, and he loved to show them to scientists visiting his laboratory. However, everything is in front of you. I spend research only in this laboratory. The same thing struck me in your laboratory, Mr. Gay-Lussak. They are only a means for work.
