摘要： 通过虫白蜡皂化法制备高级烷醇混合物探索研究,得到虫白蜡制备高级烷醇混合物的工艺优化条件:10 g虫白蜡皂化加碱4 g,皂化温度90℃,皂化时间10 h,氯化钙加入量为碱物质的量的一半,在80℃条件下,保温搅拌2 h后,抽滤,滤饼烘干,用乙醇为抽提剂,然后再用乙醇-丙酮混合溶剂将高级烷醇粗品重结晶3次,结晶体在70℃左右干燥,可得到纯度为93%的高级烷醇混合物.

Abstract: In this study policosanol was prepared from insect wax. The optimized condition is:4 g alkali was added into 10 g of wax, kept at 90℃ for 10 h for saponification, half mol of CaCl2 (according to the amount of alkali ) was added, stirred for 2 h at 80℃, then filtered with ethanol at reduced presure and dried. The filtrate was extracted with ethanol,then recrystallized the crude policosanol from ethanol-acetone mixture for 3 times and dried at 70℃, to obtain policosanol of 93% purity.

Key words: insect wax, higher fatty alcohols, sapolificationn
