【Abstract】 The one step epoxidation of fish oil with hydrogen peroxide as oxygen donor and methane acid or glacial acetic acid as active oxygen carrier is studied, and the effect of reaction conditions on the epoxidation is examined. The results show catalytic activity of cation exchange resin is higher than that of sulfuric acid; proper increase in the dosage of resin or reaction temperature can improve reaction rate; glacial acetic acid is better than methane acid as oxygen carrier; therefore under the proper reaction conditions, the epoxide number of epoxide fish oil can be above 4 5%.更多还原
