摘要
利用硫酸氢钠作为酯化反应催化剂合成了己酸异戊酯 ,确定了其最佳反应条件为 :催化剂用量为 0 2 g/0 1mol己酸 ,醇酸物质的量比为 1 5∶1,带水剂环己烷 10mL ,回流反应时间 1 5h ,己酸的酯化率可达99 3 9% .实验表明该催化剂催化效果好 ,使用量少 ,酯化率高 ,环境污染小 ,廉价易得 ,很有应用价值 .
use of sodium hydrogen sulphate as catalyst on the esterification reaction of isoamyl hexanoate was studied The suitable conditions have been found The optimum condition are selected as following :The weight of catalyst is 0 2*!g/0 1*!mol hexanoic acid ,the mole ratio of alchol to acid is 1 5∶1 and the reaction time is 1 5*!h The esterification of hexanoic acid is about 99 39% Experimental results showed that sodium hydrogen sulphate is a good catalyst of this esterification reaction ,with high catalytic activity,the used little amount,the good esterification , little waste discarged and low price It is very valuable in practice
