单、双甘油酯脂肪酶催化酯化合成高纯度 山茶籽油丙二醇单酯Synthesis of high purity propylene glycol monoesters from oil-tea camellia seed oil catalyzed by mono- and diacylglycerol lipases
为了提高丙二醇酯合成中的单酯比例,以山茶籽油脂肪酸为原料,以单、双甘油酯脂肪酶Lipase AOL、Lipase G Amano 50为催化剂酯化合成丙二醇单酯,考察了加酶量、反应温度、底物物质的量比以及摇床转速对酯化反应合成丙二醇单酯的影响,并对产物进行了鉴定,与Lipase SMG1-F278N催化酯化效果进行了比较。结果表明,Lipase AOL、Lipase G Amano 50催化酯化合成丙二醇单酯的最佳反应条件为Lipase AOL加酶量80 U/g、底物(山茶籽油脂肪酸与丙二醇)物质的量比1∶ 4,Lipase G Amano 50加酶量100 U/g、底物物质的量比1∶ 2,反...
