In order to minimize the pollution of ferrous sulfate
a by-product of titanium dioxide
and increase the yield of synthetic ester
the SO2-4/Fe2O3 nanosolid superacid has been produced by chemical precipitation and its micrographs was determined by SEM. The effect of preparation conditions of SO2-4/Fe2O3 nanosolid superacid on catalysis synthesis butyl acetate and synthesis conditions of butyl acetate were studied.From experimental data
as compared with liquid acid
SO2-4/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.
