A s comp ared w ith tra ditional e sterification, the co st of dehydrogenation wa s lower than that in p roce ss of e sterification, and the actual yield reached 82 % over 76. 9% in esterification. F inally, the situation s of in troducing foreign facilitie s for ethanol dehydrogena tion in to Ch ina and the econom ic benefit of ethanol dehydrogenation un it de signed by Tsinghua U n iversity were analyzed, and the p rogre ss of ethanol dehydrogenation technology in Ch ina were in troduced. Key word s: ethanol; hydrogenation; ethyl acetate; butanone 　　乙酸乙酯是大宗精细化工产品 ,广泛用做溶剂 , 酸乙酯需求快速增长
