COMPARISON OF CATALYTIC ACTIVITIES BETWEEN HETEROPOLY PEROXIDE AND ISOPOLY PEROXIDE

抄録

Catalytic activities of cetylpyridinium heteropoly peroxide and isopoly peroxide for epoxidation of allyl alcohols were examined in biphasic system (aq. H₂O₂-organic solvent). Heteropoly peroxide [PW₄O₈(O₂)₈]^3- (PW4) possesses partial structure of isopoly peroxide [W₂O₃(O₂)₄]^2- (W₂O₁₁), however, the reactivities for epoxidation are significantly different.
