摘　　要：研究在管道反应器中采用连续化工艺方法,以质量分数70%的双氧水进行环氧化反应合成环氧脂肪酸甲酯,其改善了传统的间歇工艺方法、釜式反应器中生产环氧脂肪酸甲酯产品所存在的诸多弊端。考察了双氧水用量、甲酸用量、反应时间、反应温度等工艺参数对产品环氧值的影响,确定了最佳工艺参数:m(脂肪酸甲酯)∶m(双氧水)∶m(甲酸)=1∶0.6∶0.05、反应时间15 min、反应温度90℃,在该条件下,所得产品的环氧值高达6.0%。Epoxidized fatty acid methyl esters were synthesized by epoxidation in pipeline reactor by a continuous process with high mass fraction of 70% hydrogen peroxide, where many disadvantages of the traditional batch process in tank reactor were overcome. The influencing factors on the epoxy value of the product, such as amount of H2O2, amount of HCOOH, reaction time, reaction temperature, were discussed. The optimum conditions were determined as follows：m（fatty acid methyl esters）：m（ H2O2 ） ：m（HCOOH） = 1：0.6：0.05 ,reaction time 15 min ,reaction temperature 90 ℃. The epoxy value of the product was up to 6. 0% under these conditions.
