含二十八烷醇的高碳醇少量制备

Preparation of Alkanols Mixture Containing Octacosanol

以虫蜡为原料 ,在乙醚中用 L i Al H4在 70～ 80℃还原 2 .5 h后得到高碳醇混合物 ,经分子蒸馏纯化 ,高碳醇收率达 96 % ,其中含二十八烷醇 16 .7%

Chinese wax rich in octacosanol was purified by molecular distillation and reduced by LiAlH 4 under pressure at 70～80℃ for 2.5h. After molecular distillation, high-carbon alkanols mixture was obtained in 96% yield, which contained 16.7% of octacosanol.
