以蜂蜡为原料制备二十八烷醇,研究了皂化温度、皂化时间、NaOH体积分数、固液比等单因素对皂化提取过程的影响,通过正交试验及其方差分析结果确定最优皂化条件为:皂化温度95℃、皂化时间3.5 h、NaOH体积分数为8%、固液比为1∶8。然后经过分子蒸馏技术纯化可以制得最高纯度为89.78%的二十八烷醇。

Octacosanol was prepared by beeswax. Temperature and time for saponification, NaOH concentration, the effect of the solid-liquid ratio on the extraction of saponification were studied. The result of orthogonal test and variance analysis showed that the optimal saponification conditions were ： 95 ℃ ,3.5 h, 8% of the mixture of NaOH and CH3CHEOH, 1：8 of solidliquid ratio. By purification and molecular distilla...
