中文摘要：

制备了酸功能化离子液体（3-磺酸基）丙基三乙基铵硫酸氢盐[N（Et）3（CH2）3SO3H]HSO4，并用FT-IR、^1H NMR和^13C NMR对其进行了表征。将其与氯乙酸组成的复合催化体系用于催化α-蒎烯一步酯化反应，详细考察了离子液体用量、反应温度、反应时间、反应物配比等因素对酯化反应的影响，得到了较佳的反应条件：n（α-蒎烯）：n[N（Et）3（CH2）3SO3H]HSO4：n（氯乙酸）：n（乙酸）5：0．6：5：14，反应温度30℃，反应时间10h。在该条件下α-蒎烯转化率为95．90％，乙酸龙脑酯选择性45．07％。并对催化体系的重复使用性进行了考察，重复使用5次时，α-蒎烯转化率仍达87．4％，乙酸龙脑酯选择性40、6％。

英文摘要：

An acidic ionic liquid, namely （3-sulfonyl）propyltriethylamine hydrosulfate [ HSO3-（CH2）3N （C2H5）3 ] HSO4 was prepared and characterized by FT-IR, ^1H NMR and ^13C NMR. Esterification of α-pinene catalyzed over the composite catalytic system of [N（Et）3（CH2）3SO3H ] HSO4-ClCH2 COOH was studied. The influences of reaction factors, such as amount of acidic ionic liquid, reaction temperature, reaction time and proportion of reactants were investigated. The optimum conditions for α-pinene esterification were obtained as follows： n （a-pinene） ： n [N （Et）3（CH2）3 S03 H ] HSO4 ： n （ chloroacetic acid ） ： n （ acetic acid ） 5 ： 0.6：5： 14, reaction temperature 30 ℃, reaction time 10 h. Under the above conditions, the conversion of α-pinene was 95.90 % and the selectivity of bornyl ester was 45.07 %. The reusability of the composite catalytic system was investigated. Under the optimum conditions, when the composite catalytic system was repeatedly used for 5 times, α-pinene conversion reached 87.4 % and the selectivity of bornyl ester was 40.6 %. α
