ABSTRACT:
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 opionally utilized include pH buffers, alkaline compounds, and solvents.
