| 摘 要： | 分别用固体超强酸S2O82-/ZrO2 和SO42-/ZrO2作催化剂，以冰乙酸和正丁醇为原料合成了乙酸正丁酯，考察醇与酸物质的量比、反应时间、反应温度、催化剂用量和催化剂焙烧温度等因素对酯化率的影响。得出反应的最佳条件为：n（正丁醇）∶n（冰乙酸）=1.3∶1.0 ,催化剂用量为冰乙酸质量的3%，反应温度115 ℃左右，反应时间30 min，固体超强酸S2O82-/ZrO2 和SO42-/ZrO2作催化剂时,乙酸正丁酯的收率分别为96.5%和90.5%。

| Abstract: | N-butyl acetate was synthesized from glacial acetic acid and n-butyl alcohol using solid super acid S2O^82-/ZrO2 and SO4^2-/ZrO2, respectively, as the catalysts. Influence of glacial acetic acid to n-butyl alcohol mole ratio, reaction time, reaction temperature, catalyst dosage ture was investigated. The optimum reaction condition was obtained as and catalyst calcination tempera- follows： glacial acetic acid to nbutyl alcohol molar ratio 1.0： 1.3, catalyst dosage 3% of the mass of glacial acetic acid, reaction temperature 115 ℃, reflux for 30 min. Esterification rate of 96.5% and 90.5% was obtained over S2O8^2-/ZrO2 and SO4^2-/ZrO2, respectively. |
