中文摘要：

制备了7种酸功能化离子液体，分别将其与氯乙酸组成复合催化体系用于催化α-蒎烯一步合成乙酸松油酯，筛选出一种催化效果较佳的离子液体[HS03-pmim]H2PO4，并用FT-IR、^1HNMR和^13CNMR对其进行了表征。考察影响反应的主要因素，确定了较佳的反应条件：n（α-蒎烯）：n（[HSO3-pmim]H2P04）：n（氯乙酸）：n（乙酸）=5：0．9：5：14，反应温度40℃，反应时间10h。在此条件下，α-蒎烯转化率为85．6％，乙酸松油酯质量分数为36．0％。该催化体系可重复使用，重复使用5次时，α-蒎烯转化率为83．5％，乙酸松油酯质量分数仍达33．7％。

英文摘要：

Seven acidic functional ionic liquids were prepared and used as catalysts in α- pinene esterification. A suitable ionic liquid [HSO3-pmim] H2 PO4 was obtained and characterized by FT-IR, ^1H NMR and ^13C NMR. The influences of factors on a-pinene esterification results were investigated and the obtained optimum conditions were n（α-pinene） ： n（[HSO3-pmim]H2PO4） ： n（chloroactic acid） ： n（acetic＇acid）=5 ： 0. 9 ： 5 ： 14,reaction temperature 40℃ and reaction time 10 h. Under above conditions, the con- version of α-pinene was 85.6% and the selectivity of terpinyl acetate was 36.0%. When the composite catalytic system was reused for 5 times, a-pinene conversion and selectivity of terpinyl acetate were still 83.5% and 33.7% respectively.
