Abstract: In order to minimize the pollution of ferrous sulfate, a by-product of titanium dioxide, and increase the yield of synthetic ester, the SO^2-₄/Fe₂O₃ nanosolid superacid has been produced by chemical precipitation and its micrographs was determined by SEM. The effect of preparation conditions of SO^2-₄/Fe₂O₃ nanosolid superacid on catalysis synthesis butyl acetate and synthesis conditions of butyl acetate were studied.From experimental data,as compared with liquid acid, SO^2-4/Fe₂O₃ nanosolid superacid showed higher catalytic performance in catalytic synthesis of butyl acetate,and the yield of butyl acetate was obviously increased in the same reaction time.
