摘要
天然油脂在无溶剂加压（约０．１５ＭＰａ）条件下，经甲酸（８５％）、双氧水（５０％）环氧化，一步合成增塑剂兼稳定剂环氧化油脂，得微黄色油状透明液体；环氧大豆油和环氧葵子油的环氧值均在６．２％～６．６％，环氧玉米油的环氧值６．０％～６．４％；碘值小于３ｍｇ／ｇ；精油转化率１０４％～１０８％。
Some vegetable oils were epoxidized at 60℃ for 6 hours under pressure of0. 15MPa and at the feed ratio(by weight)of oil l H2O2(50%) : HCOOH(85%):H2SO4 (98%)=100: 50:9:2 The epoxide numbers of the epoxidized soy bean oil,sunfloweroil,as well as corn oil were 6.2%～6.6%and 6.O%～6.4%,respectively. The iodine num-bers of the epoxidized oils were less than 3mg/g.
