Abstract: Carboxylic acid was peroxidized in organic solvents catalyzed by lipase and glycidol was synthesized from allyl alcohol catalyzed by acid peroxide. The optimum conditions (enzyme source, enzyme concentration, acid, acid conce ntration, reaction medium and reaction temperature, et al) were screened out. Under the optimumconditions, a conversion of 67% was achieved.

Key words: lipase, epoxidation, allyl alcohol, glycidol
