在十二水合硫酸铁铵存在下,正丁醇和硬脂酸发生酯化反应,高收率地合成了硬脂酸正丁酯.研究了十二水合硫酸铁铵和正丁醇用量及反应时间对收率的影响,当硬酯酸用量为7.1g(28mmol),硬酯酸、正丁醇和硫酸铁铵的摩尔比为1:8:0.124,回流分水2h,酯收率达98.8%.

n-Butyl stearate was synthesized in high yield by esterification of n-butyl alcohol with stearic acid in the presence of ammonium ferric sulfate dodecahydrate. The effects of the amount of ammonium ferric sulfate dodecahydrate, n-butyl alcohol and reaction time on the yield have been investigated. The yield of the ester could reache 98.8% under amount of substance ratio of stearic acid, n-butyl alcohol and ammonium ferric sulfate were 1∶8...
