Title: The Catalytic Synthesis of Butyl Phenylaceate by SO_4~(2-) /TiO_2/La~(3+) Rare-earth Solid Superacid
Abstract: The synthesis of butyl phenylaceate with n butanol and phenylacetic acid as reactants and rare earth solid superacid SO 2- 4/TiO 2/La 3+ as catalyst had been studied.The influent factors of reaction were investigated.The results showed that the appropriate conditions should be:weight of catalyst was 2%(weight of phenylacetic acid if 0.2 mol),the molar ratio of n butanol to phenylacetic acid was 2.0∶1,the reaction time was 3.0 h,the taking water reagent(Toluene) was 15 mL.The yield of butyl phenylaceate was about 98.5%.
