摘要
以硅钨酸作催化剂制备乙酸乙酯,讨论了催化剂用量、反应时间、醇酸摩尔比对收率的影响,并与硫酸催化剂进行对比,实验收率为92.21%,超过硫酸水平,并对催化剂的重复使用进行了探讨。
It has studied the catalytic activity of silicotungstic acid as catalyst in synthesis ethyl acetate. Discussed the quantity of catalyst, the time of reaction and effect of the alcohol and ratio of acid on rate of the reaction. Under the optimum conditions, rate of production was 92.21%, which is better than using the sulphurie acid. And it was studied the reusing of catalyst.
