摘要: 选用对甲苯磺酸作为酸催化剂,采用原位法(一步法)合成环氧脂肪酸甲酯。结果表明原位法不仅操作简单、步骤少、安全,与两步法相比,环氧率更高,且更能遏制开环率。通过正交试验表明最佳反应条件为:脂肪酸甲酯双键、甲酸、双氧水物质的量之比为1:0.5:1.4;反应温度 65℃;反应时间 4 h,产品环氧值最高可达到6.23%。

Abstract: Synthesis of epoxy fatty acid methylesters from insitu method (one pot) was studied using p-toluenesulfonic acid as catalyst. The results showed that insitu method has high efficiency, easy operation and higher security. The optimum reaction conditions were: n(double bond of methyl ester):n(methane acid):n(aquae hydrogendioxidient)=1:0.5:1.4; reaction temperature 65℃ and reaction time 4 h. The epoxy value of the final product can reach 6.23%.

Key words: methyl ester, epoxy fatty acid methyl ester, insitu, epoxidation, plasticize
