摘要： 以十八胺聚氧乙烯醚类化合物 (AC 1812，AC 1815，AC 1820，AC 1830) 为阳离子，合成了7种长链脂肪胺类酸性离子液体。通过FT-IR 、1H NMR和13C NMR对它们的结构进行了表征，并分别用于催化α-蒎烯一步酯化合成松油醇，其中离子液体十八胺聚氧乙烯醚硫酸盐（\[AC 1815\]+\[HSO4\]-）的催化效果较佳。以该离子液体为例考察影响反应的因素，确定了较佳的反应条件为： n(α-蒎烯) ∶ n(离子液体) ∶ n (氯乙酸) ∶ n(水) =1 ∶ 0.05 ∶ 1 ∶ 5，n(α-蒎烯) = 0.06 mol，反应温度 80 ℃，反应时间 8 h。在此条件下，α-蒎烯转化率为94.0 %，松油醇产率为 59.8 %。该催化剂可重复使用，重复使用 5 次时，α-蒎烯转化率为 91.5 %，松油醇产率仍达 56.8 %。

Abstract: Seven acidic ionic liquids were synthesized using octadecylamine ethoxylates (AC 1812, AC 1815, AC 1820, AC 1830) as cation and characterized by FT-IR, 1H NMR and 13C NMR. The ionic liquids were used as catalyst in synthesis of terpinol by hydration of α-pinene. It was found that the ionic liquid polyoxyethylene octadecylamine ether sulphate (\[AC 1815\]+\[HSO4\]-) was an excellent catalyst for synthesis of terpinol. Using this ionic liquid as catalyst, the effects of reaction conditions on α-pinene hydration results were investigated. The obtained optimum conditions were n(α-pinene) ∶ n(ionic liquid) ∶ n(chloroactic acid)∶n(water)=1 ∶ 0.05∶ 1 ∶ 5, n(α-pinene)=0.06 mol, reaction temperature 80 ℃ and reaction time 8 h．Under the optimum conditions, the conversion of α-pinene was 94.0 % and the yield of terpinol was 59.8 %. When the catalyst was reused for 5 times，the conversion of α-pinene and the yield of terpinol were still 91.5 % and 56.8 % respectively.
Key words: α-pinene; acidic ionic liquid; hydration; terpinol; catalysis
