Abstract:
The synthesis of butyl butyrate with n-butanol and butyric acid as reactants and solidsuper acid as TiO2/SO2-4 catalyst had been studied. The influent factors of rcaction were investigatcd.The results showed that the appropriate conditions should be: weight of cattalyst was 2. 0g(weight of bulyric acid if 0. 2mol) , molar ratio of n-butanol to butyric acid was 1. 8 ∶ 1, reaction time was 2. 0h, the taking water reagent (toluene)was 15mL. The yield of butyl butyrate was about 97. 4% .
