Abstract
It has shown the method of synthesis of tungstophosphoric acid and studied the synthesis of ethyl acetate with ethanol and acetic acid as raw material,tungstophosphoric acid as catalysts.The experimental results indicate the optimum condition as follows:the ratio of acid to alcohol is 2.0∶1～2.5∶1,the quantity of catalyst is 2.0%～2.5% of the quantity of acid,the time of reaction is 4.0?h,the rate of production is 94.6%.
