| 摘 要： | 用三氯化铝、三氯化锑与卤化1-烷基-3-甲基咪唑盐〔[Cnm im]X〕制备了3种酸性离子液体复合催化剂{[C2m im]B r-A lC l3/SbC l3、[C4m im]C l-A lC l3/SbC l3和[C8m im]C l-A lC l3/SbC l3},并用于催化松节油聚合反应,结果表明,以[C4m im]C l-A lC l3/SbC l3的催化活性为佳。以[C4m im]C l-A lC l3/SbC l3为催化剂,考察了m(松节油)∶m(甲苯)∶m{[C4m im]C l}∶m(A lC l3)∶m(SbC l3),反应温度和反应时间等条件对反应结果的影响。在m(松节油)∶m(甲苯)∶m{[C4m im]C l}∶m(A lC l3)∶m(SbC l3)=15∶15∶2∶3∶1.5,反应温度-10℃,反应时间4~5 h较佳工艺条件下,固体树脂产物的收率为64%,软化点为104℃。

| Abstract: | From AlCl_3,SbCl_3 and 1-alkyl-3-methylimidazolium halide([C_nmim]X) the acidic composite catalytic systems of ionic liquids ([C_2mim]Br-AlCl_3/SbCl_3,[C_4mim]Cl-AlCl_3/SbCl_3 and [C_8mim]ClAlCl_3/SbCl_3) were synthesized and used to catalyze the polymerization of turpentine.Among these systems [C_4mim]Cl-AlCl_3/SbCl_3 has the highest catalytic activity.Using [C_4mim]Cl-AlCl_3/SbCl_3 as catalyst,under the optimum reaction conditions of m(turpentine)∶m(toluene)∶m([C_4mim]Cl)∶m(AlCl_3)∶m(SbCl_3)=15∶15∶2∶3∶1.5,reaction temperature-10 ℃ and reaction time 4～5 h,the yield of solid resin was 64% and its softing point could reach 104 ℃. |
