有机介质中脂肪酶催化合成亚麻酸甘油酯
Lipase-catalyzed Synthesis of Linolenic Acid Glyceride in Organic Medium
【摘要】 研究固定化脂肪酶在有机溶剂中催化亚麻酸甘油酯的合成反应。考察了有机溶剂、酯化温度、物料比、催化剂用量、酯化时间等因素对酯化率的影响。结果表明:以正己烷为溶剂、酯化温度60℃、酸醇摩尔比1:2.5条件下、反应24h,亚麻酸甘油酯化率为90%以上。
【Abstract】 linolenic acid glyceride was synthesized by the catalyst of immobilized lipase.The effect of organic solvent,esterfication temperature and the ratio of materials,the amounts used of solvent and catalyst,time of reaction have been studied.the optimal condition that N-hexane as a solvent and the temperature was 60℃,mole mass ratio of acid and alcohol was 1∶(2.5),the reaction time was 24 hours.the esterfecation rate of linolenic acid glyceride was reached about 90%.
