| Abstract: | The solid super acid S2O8^2-/ZrO2-SnO2 is prepared, the mass fraction of SnO2 is studied, and it is applied on the catalytic synthesis of isoamyl hexanoate. The optimum conditions are selected as following：The mass fraction of SnO2 is 2.0%, the weight of catalyst is 1.0 g/0.10 mol hexanoic acid ; the mole ratio of acid and alchol is 1 ： 2.0 and the reaction time is 2.5 hour. The estefification of hexanoic acid is above 96% and it doesnt pollute the environment. |
