| Abstract: | The solid super acid SO4^2-/ZrO2 -Ce2O3 is prepared. The mass fraction of Ce2O3 is studied. It is applied on the catalytical synthesis of isoamyl butyrate. The optimum conditions are selected as following： The mass fraction of Ce2O3 is 2.0%, the weight of catalyst is 1.0g/0. 10 mol butyhic acid; the mole ratio of acid and alchol is 1： 2. 0 and the reaction time is 2.5 hour. The easterification of butylatic acid is about 96%. |
