| Abstract: | The solid super-acid SO4^2-/TiO2 was used as catalyst for the synthesis of n-butyl acetate. It was researched that the molar ratio of n-butanol to ethanoic acid, time quantity of catalyst had influenced upon yield of esterification reaction. The influent actors of reaction were investigated. The results showed that the solid super-acid SO4^2-/TiO2 was high catalytic activity, easy to part for and do not corrode to equipment, discharging a nothing to contaminate,and so on. In the best condition, the highest esterification yield of n-butyl acetate was about 99.3 %. |
