Abstract: Some heteropoly acids were used as catalyst for epoxidation of soybean oil and corn oil by hydrogen peroxide and formic acid. Among them the CPW, i.e.[(C5H5)N-(CH2)15CH3]3PW12O40 was found to be the most active one. The epoxidized soybean oil and corn oil have epoxy value of 6.6% and 6.4%, respectively, with iodine value less than 6 g(I2)/100g.

Key words: epoxidation, soybean oil, corn oil, heteropoly acid
