| Abstract: | Solid phosphoric acid catalyst was prepared by impregnation method and their catalytic activity for synthesizing ethyl acetate was investigated.The effects of varied factors in solid phosphoric acid preparation and esterification have been analyzed.The results of test indicate that the better reaction conditions are: When the amount of catalyst is 30%(based on mass of acetic acid) and the molar ratio of acetic acid to alcohol is 1:3,the yield can reach 70.3% after 2 hours. |
