以蔗蜡为原料制备及纯化二十八烷醇

Preparation and Purification of Octacosanol from Sugarcane Wax

以蔗蜡为原料,采用醇相皂化法制备长链脂肪醇,通过重结晶法获得高纯度二十八烷醇,采用毛细管气相色谱测定各阶段产物中二十八烷醇含量,实验结果表明:长链脂肪醇的得率为24%,其中二十八烷醇含量为66.50%,经分离纯化后的小试样品中二十八烷醇含量为88.96%。

Used sugarcane wax as raw material, the long chain aliphatic alcohol mixture was obtained by saponification within ethanol phase, and high pure octacosanol was obtained by recrystallization from the mixture. The octacosanol content of the sample were determined by capillary gas chromatography. The resuits were as follows： the production ratio of long chain aliphatic alcohol is 24% and the octacosanol content in the mixture is 66.50%, the octacosanol content in the purified sample is 88.96%.
