Vladimir Nikolayevich Ipatieff

Died 29 Nov 1952 at age 85 (born 21 Nov 1867).Russian-American chemist who was one of the first to investigate high-pressure catalytic reactions of hydrocarbons and who developed a process for manufacturing high-octane gasoline. While studying in Munich (1897) Ipatieff achieved the synthesis of isoprene, the basic unit of the rubber molecule. Upon return to Russia he worked particularly on the use of high-pressure catalysis and of metallic oxides as catalysts. With these techniques, he helped to establish the petrochemical industry in both pre- and post-revolutionary Russia. Before WW I, he had synthesized isooctane, and had polymerized ethylene. After moving to the U.S. (1930), Ipatieff showed how to convert low-octane gasolines into high-octane by 'cracking' hydrocarbons at high temperatures.
