| Abstract: | In this paper,ethyl acetate has been synthesized by ethanol and acetic acid using P-Mo-V heteropoly acids H6PMo9V3O40 as catalyst,and the effect of the molar ratio of ethanol to aceticacid,the quantity of the catalysts and the reaction time on acetate yield is discussed.The results indicate that H6PMo9V3O40 is a good esterication catalyst and that the optimum reaction conditions are:the ratio of ethanol to aceticacid is 2∶1,the quantity of P-Mo-V catalyst is 3.5% of the reactants,the reaction time is 25 min,the ethyl aceate yield is up to 80%. |
