在一水硫酸氢钠存在下由苯甲酸和乙醇合成了苯甲酸乙酯。当苯甲酸、乙醇和硫酸氢钠的质量配比为 1∶8∶0 86,回流 8h时 ,酯收率达 93%。
Ethyl benzoate was synthesized from benzoic acid and ethanol in the presence of sodium bisulfate monohydrate. When the mass ratio of benzoic acid, ethanol and sodium bisulfate is 1: 8: 86, the yield of ester reaches 93% at reflux time of 8h.
