发明名称 Epoxidation of ricinic compounds using a phase-transfer catalyst
摘要 Unsaturated or polyunsaturated, conjugated or nonconjugated hydrocarbons are reacted with an oxidizing agent including hydroperoxides and monopersulfate compounds in the presence of phase-transfer catalysts. Suitable hydrocarbons include ricinic compounds such as castor oil and dehydrated castor oil. The phase-transfer catalysts include novel tungsten peroxo complexes, such as quaternary ammonium tetrakis (diperoxotungsto) phosphates, and crown ethers. Other additives utilized include pH buffers and alkaline compounds including alkali metal and alkaline earth metal carbonates, and solvents.
