Abstract: Epoxidized safflower seed oil was prepared using hydrogen peroxide as oxidant, formic acid as oxygen carrier, and strong acidic cation exchange resin as catalyst. The optimized reaction conditions are:with the presence of ethylene diamine tetraacetic acid as stabilizer, the precursor ratio for m(safflower seed oil)∶m(88% formic acid)∶m(H2O230%)∶m(cation exchange resin) is 1∶0.244∶1.665∶0.035, the reaction temperature is 60 ℃, the reaction time is 6 h and the stirring rate is 400 r/min, the epoxy value is above 7.0.
Key words: safflower seed oil, Epoxidation technology, cation exchange resin, H2O2, performic acid
