摘要
用相转移催化剂对硫酸铝催化法合成环氧大豆油技术进行了改进研究。实验结果表明,比没有改进的硫酸铝催化法合成环氧大豆油产品的环氧值有了很大的提高,同时大大缩短了反应时间,实验确定的最佳投料比为：m（大豆油）∶m（27%双氧水）∶m（甲酸）∶m（硫酸铝）∶m（相转移催化剂）=1∶（0.8-1.0）∶（0.13-0.15）∶（0.075-0.085）∶（0.0001-0.001）。环氧大豆油产品环氧值在8.0%左右,酸值为0.40-0.50 mgKOH.g-1,色泽较浅。
The synthesis technology of epoxy soybean oil by aluminum sulfate catalyst method was improved with the phase transfer catalyzer. The experiment result showed that the epoxy value of synthesizing epoxy soybean oil with the improved method was higher than that of the product without the phase transfer catalyzer, and reaction time was shortened. The optimum scale of crude material was that the scale of soybean oil, hydrogen peroxide（27%）, formic acid, aluminum sulfate and phase transfer catalyst was 1 ： （0.8- 1.0） ： （0.13-0.15） ： （0.075-0. 085）：（0. 0001-0. 001）. The epoxy value of the epoxy soybean oil was about 8.00%. Acid value was about 0.40-0.50 mgKOH·g^-1. The color of the product was pale yellow.
