摘　　要：以葵花籽油为原料,碱法异构化合成共轭亚油酸。通过单因素试验以及三因素三水平正交试验,研究了溶剂种类、反应时间、反应温度和催化剂用量对CLA生成量的影响,结果表明,当以1,2-丙二醇为有机溶剂,溶剂的质量比m(葵花籽油)∶m(丙二醇)=1∶3,反应温度为170℃,反应时间为2.5 h,加碱量与皂化值的质量比为2.2时,CLA的生成量可以达到较佳值。在较优条件下重复实验,得到较佳条件下的CLA产率为47.80%。The conjugate linoleic acid（ CLA） was prepared by the alkali isomerization with sunflower oil as raw material. Effects of solvent varieties,reaction time,reaction temperatures,and catalyst dosages on the yield of CLA were analyzed by the single factor experiment and orthogonal experiment with three factors and three levels. The results showed that optimized conditions were as following,1,2-propylene glycol as solvent,the ratio of sunflower oil and solvent 1 ∶ 3,the reaction temperature 170 ℃,the reaction time 2. 5 h,and the ratio of alkali and saponification equivalent 2. 2. The yield of CLA was 47. 80% under the optimized conditions.
