| Abstract: | The synthesis of butyl acetate from n butanol and acetic acid with rare earth solid superacid SO 2- 4 /TiO 2/La 3+ as catalyst was studied. The influential factors of reaction were investigated. Results show that the appropriate conditions are: weight of catalyst 0.6 g; molar ratio of n butanol to acetic acid 1.6∶1; reaction time 2.5 h; water carrying reagent 7 mL. The yield of butyl acetate is about 96.2%. |
