Abstract
Benzoic acid ethyl was synthesized successfully with benzoic acid and ethanol as starting materials in the presence of catalyst 4-dimethylaminopyridine and 1,3-dicyclohexyl carbodiimide as dehydrating agent by refluxing.The factors to yield of benzoic acid ethyl ester had been discussed on proportion of benzoic acid,ethanol and 4-dimethylaminopyridine,and reacting time.Result demonstrated that the best condition for preparation of benzoic acid ethyl was that the proportion of benzoic acid ethanol,4-dimethyl aminopyridine and dicyclohexylcarbodiimide in amount was 1: 3: 0.08: 1.2 for 3 hours.
