CN107043794A 一种酶催化红花油醇解制备脂肪酸乙酯的方法 无效 - 驳回

一种酶催化红花油醇解制备脂肪酸乙酯的方法
摘要：
本发明公开了一种酶催化红花油醇解制备脂肪酸乙酯的方法，所述方法是以红花油和乙醇为反应底物，以能溶解反应底物的有机溶剂为反应介质，在脂肪酶的作用下，于25‑60℃进行醇解反应，反应完全后，将反应液分离纯化，获得脂肪酸乙酯；本发明酶催化反应条件温和，反应产率高(由90％提高95％以上)，下游分离简单(化学法需要加酸中和碱性催化剂)，能耗低(化学法温度高)，环境污染小(生物法废水减少80％以上)，适合工业化生产。
摘要（英）：

The invention discloses a method for preparing fatty acid ethyl ester by catalyzing safflower oil alcoholysis through enzyme. The method is characterized in that safflower oil and ethyl alcohol are taken as reaction substrates, an organic solvent which can solve the reaction substrates is taken as a reaction medium, alcoholysis reaction is performed at a temperature of 25-60 DEG C under action of lipase; and after complete reaction, reaction liquor is separated and purified to obtain the fatty acid ethyl ester. The method has the advantages of gentle enzyme catalysis reaction condition, high reaction yield (increased to be 95% or higher from 90%), simple downstream separation (a chemical process requires adding acid to neutralize a basic catalyst), low energy consumption (high temperature is needed in the chemical process), little environmental pollution (biological-process wastewater is reduced to be 80% or higher), and suitability for industrial production.
