Sergei Vasiljevich Lebedev
Sergei Vasiljevich Lebedev (July 25, 1874 – May 1, 1934) was a Russian/Soviet chemist and the inventor of one type of synthetic rubber.
Additional recommended knowledge
Lebedev was born in Lublin and went to school in Warsaw. In 1900, he graduated from St. Petersburg University and found work at the Petersburg Margarine Factory.
Starting in 1902, Lebedev moved from university to university in Russia, starting at the Saint-Petersburg Institute for Railroad Engineering. In 1904, he returned to St. Petersburg University to work under Aleksey Favorsky. In 1915, he was appointed Professor at the Women's Pedagogical Institute in St. Petersburg. After 1916, he was a Professor of Saint Petersburg Academy for Military Medicine. In 1925, he became the leader of the Oil Laboratory (after 1928, the Laboratory of Synthetic Resins) at St. Petersburg University.
He died in Leningrad and is interred in Tikhvin Cemetery.
Lebedev's main works are devoted to polymerisation of diene hydrocarbons. He was first to research the polymerisation of butadiene (1910-1913). In 1910, Lebedev was the first to get synthetic rubber based on poly-butadiene. His book Research in polymerisation of by-ethylene hydrocarbons (1913) became the bible for studies of synthetic rubber.
After 1914, he studied polymerisation of ethylene monomers, leading to modern industrial methods for manufacturing of butil synthetic rubber and poly-isobutylene.
Between 1926 and 1928, Lebedev developed a single-stage method for manufacturing butadiene out of ethanol.
In 1928, he developed an industrial method for producing synthetic rubber based on polymerisation of butadiene using metallic sodium as a catalyst. This method became the base for the Soviet industry of synthetic rubber. The Soviets lacked reliable access to natural rubber, making the manufacture of synthetic rubber important. First three sinthetic rubber plants were launched in 1932-33. For butadiene production they used grain or potato ethanol as a feedstock. It caused a number of jokes about "Russian method of making tyres of potato".
By 1940, the Soviet Union had the largest synthetic rubber industry in the world, producing more than 50,000 tons per year. During World War II, Lebedev's process of obtaining butadiene from ethyl alcohol was also used by the German rubber industry.
