The formation of epoxy derivatives as intermediate products in the oxidation of allyl alcohol, ally] formate, and allyl acetate in acetic acid was proved. Intermediate epoxy compounds undergo further transformations: They react with acetic acid to give glycerol esters or are converted into polyethers of glycerol and its esters. The rate constants for transformations of 2,3-epoxypropanol, 2,3-epoxypropyl formate, and 2,3-epoxypropyl acetate along these pathways were measured. Higher selectivity of glycerol ester formation from allyl formate was substantiated.
