摘要
在一水硫酸氢钠存在下 ,由正丁醇和硬脂酸酯化合成高收率的硬脂酸正丁酯 ,研究一水硫酸氢钠用量、正丁醇用量和反应时间对硬脂酸正丁酯的影响 .硬脂酸、正丁醇和硫酸氢钠的物质的量之比为 1∶4∶0 .0 7,回流分水 2h ,酯收率达 96.4% .
n\% Butyl stearate was synthesis in high yield by esterification of \%n\% butyl alcohol with stearic acid in the presence of sodium bisulfate monohydrate. The effects of the amount of sodium bisulfate monohydrate, the amount of \%n\% butyl alcohol and reaction time on the yield of \%n\% butyl stearate have been investigated. The yield of the ester could reache 96.4% under amount of substance ratio of stearic acid, \%n\% butyl alcohol and sodium bisulfate were 1∶4∶0.07, refluxing and water segregating for 2 h.
