摘要：

The composite solid superacid SO2-4/TiO2-Fe2O3(nTi∶nFe=2∶1)was prepared by the method of deveiopmental sol-gel and wet impregnation.First reported the composite solid superacid catalysis synthesized isobutyl butyrate for buthlacid and isobutyl alcohol.It was researched that the acid-alcohol rate,time,quantity and repeatly applicatiom of catalyzes had imflune upon yield of esterication reaction.The influent actors of reaction were investigated.The results showed that teh appropriate conditions should be:weight of cstalyst was 10g;molar ratio of isobutyl alcohol to buthlacid was 18∶1;reaction time was 30h;the taking water reagent (Benzene) was 15ml.The yield of isobutyl butyrate was about 985%.The acid value was: 1602<Ho< 1452.
