采用直接合成法制备了4种离子液体，并作为催化剂采用一锅法催化合成系列羧酸正丁酯，结果表明，离子液体[C₃SO₃Hnmp]HSO₄催化合成丁酸正丁酯活性最高。采用溶胶-凝胶法制备固载化离子液体[C₃SO₃Hnmp]HSO₄，利用响应曲面法（RSM）对反应条件进行优化，结果表明，反应温度为120℃、反应时间为3.19 h、酸醇摩尔比为1.14：1、催化剂质量为正丁醇质量的7%时，丁酸正丁酯预测收率为97.21%，优化条件下实验收率为97.10%。固载离子液体[C₃SO₃Hnmp]HSO₄循环使用6次后仍保持较高的催化活性。

Four kinds of functionalized ionic liquid are prepared through direct synthetic method and used to catalyze the synthesis of series n-butyl carboxylate via one-pot method.The results show that ionic liquid[C₃SO₃Hnmp]HSO₄ exhibits the highest activity in catalyzing the synthesis of n-butyl butyrate.The immobilized[C₃SO₃Hnmp]HSO₄ is obtained through sol-gel method and the reaction conditions are optimized by means of response surface methodology (RSM).The results show that the predicted yield of butyric acid n-butyl ester reaches 97.21% and the actual yield achieves 97.10% under the optimized reaction conditions that reaction temperature is set at 120℃,reaction lasts for 3.19 h,n(butanoic acid):n(normal butanol)=1.14:1,catalyst dosage is 7% (based on normal butanol).The immobilized ionic liquid[C₃SO₃Hnmp]HSO₄ remains high activity after reused for 6 times.
