摘　　要：以甲醇钾为催化剂催化共轭化葵花籽油甲酯制备共轭亚油酸甲酯。研究不同催化剂用量、温度、时间、含水量等因素对共轭化反应的影响。结果表明,最佳工艺条件为:甲醇钾5%,温度130℃,原料含水量小于0.2%,在真空条件下反应3 h,共轭转化率可达到95%以上。The methyl ester of conjugated linoleic acid was prepared by using methyl ester of sunflower oil with KOCH3 as reaction catalyzer. The catalyzer dose, temperature, time and water content on the conjugation were investigated. It is shown that the optimized conditions are catalyzer 5%, water 0.2%, temperature 130 ℃, reaction time 3 h in vacuum. The conjugation rate is 95 % under the optimal conditions.
