摘要
在微波辐射下以六水合氯化铁为催化剂合成了乙酸乙酯．探讨了酸醇物质的量比、氯化铁用量、微波辐射时间和微波功率对酯化率的影响．结果表明最佳反应条件为：酸醇物质的量比3：1，氟化铁用量为酸醇总质量的4．0％～5．5％（1．2g），微波功率280W，微波辐射时间8min．反应酯化率可迭89．2％．
By using the technique of microwave radiation, and under the catalyzing of ferric chloride, ethyl acetate can be synthesized fast. This paper investigated the effects to esterification by discussing the ratio of acid and sterols, the dosage of ferric chloride, time of microwave radiation and power of microwave. The result showed that the best reacting conditions were as follows.the ratio of acid and sterols was 3 ： 1 （mol/mol） ,the dosagc of catalyst was 4.0%-5.0%（which is included in total of acid and sterols）,the power of microwave was 280 W,the time of microwave radiation was 8 min. The rate of transforming may reach 89.2 %.
