摘　　要：以AlCl3改性阳离子交换树脂为催化剂,甲酸为活性氧载体、双氧水为活性体合成环氧大豆油.考察了AlCl3改性阳离子交换树脂、双氧水、甲酸、反应温度、反应时间等因素对环氧化反应的影响,确定了最佳反应工艺为:AlCl3改性阳离子交换树脂、双氧水、甲酸用量分别为大豆油质量的14%、90%、15%,反应温度55℃,反应时间5.0h,环氧大豆油的环氧值达到6.21%;AlCl3改性阳离子交换树脂使用四次后环氧值为6.18%,具有良好的重复使用性能.Peroxyformic acid was prepared by the in-situ reaction of formic acid and H2O2,with cation exchange resin modified by AlCl3 as catalyst. The dose of formic acid,ation exchange resin modified by AlCl3 and H2O2,reaction temperature,and reaction time were selected,and the optimum process parameters is the dose of ation exchange resin modified,H2O2,and formic acid is14%,90%,15% of soybean oil quality,respectively,reaction time is 5. 0 h,reaction temperature is 55 ℃. In this condition,the epoxy value reached 6. 21%of epoxy soybean oil. The epoxy value of epoxy soybean oil can reach6. 18% after the cation exchange resin modified by AlCl3 repeated use 4 times. The result shows that cation exchange resin modified by AlCl3 has good repeated use performance.
