| 摘 要： | 合成了硝酸正丁胺（N_4NO_3）、醋酸正丁胺（N_4AC）、醋酸正丙胺（N_3AC）和醋酸乙胺（N_2AC）4种胺型离子液体,采用~1HNMR对其结构进行了表征。以上述胺型离子液体为催化剂,冰醋酸和正己醇为原料,环己烷为带水剂,通过酯化反应制备了乙酸己酯。考察了催化剂种类、反应温度和反应时间等因素对乙酸己酯酯化率的影响,优化了反应工艺。最佳反应条件为：15mL环己烷为带水剂,n（冰醋酸）：n（正己醇）：n（N_4NO_3）=1：1.2：0.1,反应温度为95℃,反应时间为4.5h,乙酸己酯的酯化率可达90.52%。

| Abstract: | Four ammonium ionic liquids,n-butylamine nitrate(N_4NO_3),n-butylamine acetate(N_4AC), n-propylamine acetate(N_3AC) and ethylamine acetate(N_2AC) were synthesized.Their structures were identified by ~1HNMR.The hexyl acetate was synthesized from n-hexanol and acetic acid using the ammonium ionic liquids as the catalyst by direct esterification.The influences of catalyst,reaction temperature and reaction time were investigated. The proper reactions condition was as follow:using 15mL cyclohexane as water carri... |
