Abstract

The preparation process of solid superacid SO4 /ZrO2-SnO2 was studied on coprecipitation method.The results indicated that the optimum preparation conditions of SO4 /ZrO2-SnO2 should be the concentration of H2SO4 1.0 mol/L,impregnation time 24 h,baking temperature 500℃ and baking time 2h.Furthermore,its structure was characterized by IR spectroscopy and Hammett,catalytic activity was studied by the esterifieation reaction of isoamyl acetate
