摘要
采用植物甾醇与硬脂酸直接酯化的方法合成了甾醇硬脂酸酯.通过正交实验法,筛选出酯化反应最优工艺条件为n(甾醇)∶n(硬脂酸)=1∶1.2(mol/mol),反应温度135℃,反应时间7h,酯化率可以达到87.8%.研究了甾醇硬脂酸酯的重结晶精制工艺.
Phytosterols stearic was synthesized by direct esterification of phytosterols and stearic acid .Through factorial design, the optimal synthetic conditions were obtained as follows: molar ratio of phytosterols to stearic acid was above 1∶1.2; reaction temperature was 135℃ and reaction time was 7 h . The yield of esterification was 87.8%. Recrystallization method of phytosterols stearic was researched.
