摘要
文章采用TiO2/SO42-固体超强酸为催化剂来合成乙酸正丁酯,考察了催化剂用量、酸醇物质的量之比、反应时间等因素对酯化率的影响,结果表明,TiO2/SO42-固体超强酸催化剂活性高,易分离,对设备不腐蚀,排放无污染等优点;在最佳反应条件下,酯化率可达99.3%。
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 %.
