摘　　要：选择含量为50%左右的茄尼醇半成品为原料,通过脱蜡提取高纯度茄尼醇,探讨脱蜡溶剂种类、溶剂比、脱蜡温度和时间对实验过程的影响。采用最小方差法关联实验数据、牛顿法迭代,实验及关联结果:在脱蜡实验中,将10g茄尼醇半成品溶于200 ml丙酮中,在7℃加热搅拌至完全溶解,缓慢降温至10℃,静置2 h,可获得纯度较高的产品,如茄尼醇的纯度为65%,则收率超过75%。Solanesol was refined from intermediate product（purity of solanesol 50% ）by dewaxing. The effect of ratio and the type of dewaxing solvent, temperature and time on the experimental process was discussed. The experimental data were correlated by using min- imum square the experimental process method and iterated by Newton-Lapuson method. Results of experiment and correlation show that 200 ml acetone was inputed in 10 gram intermediate product of solanesol, dissolved completely with agitation at 70 ℃, then standing 2 hours at 10 ℃, more than 65% purity of solanesol and more than 85% extractoin ratio can be achieved.
