Kharichkov, Konstantin Vasil’evich
Born 1865; died Aug. 6, 1921. Russian organic chemist.
After graduating from St. Petersburg University in 1892, Kharichkov worked in Baku and Groznyi. He was a professor at the higher women’s courses in Tbilisi from 1909 to 1914 and at the university in Rostov-on-Don from 1917. Kharichkov’s scientific works are devoted to petrochemistry. Kharichkov proposed a method of processing high-paraffin mazut from petroleum extracted at Groznyi, which resulted in its widespread use as boiler fuel. He also developed a method of separating high-molecular-weight petroleum hydrocarbons by fractional sedimentation, which he called cold petroleum fractionation (1903).
