Optimization in the Synthesis of Ethyl Acetate

The synthesis of ethyl estate reported in organic chemistry experiment which is edited by Wangqinglian is as follows:acetic acid and ethanol are used as raw materials,concentrated sulfuric acid as catalyst,ethyl estate can be synthesized at the yield of 45%.The synthesis conditions were optimized to improve the yield.The results show that the yield could be improved to 60% when the molar ratio of acetic acid to ethanol is 1:1.5,refluxing times is 40 mins,reaction temperature on 80-83 when heated by water bath.
