| 摘 要： | 采用AlCl3和[Bmim]Cl不同摩尔比的[Bmim]C1-xA1C13离子液体为催化剂,研究了不同条件下1-十二烯与苯的烷基化反应。实验结果表明,以A1Cl3和[Bmim]Cl的摩尔比为2.0([Bmim]Cl-2A1C13)的离子液体为催化剂,在反应温度25℃、反应时间30 min,苯、烯及离子液体的摩尔比为5︰1︰0.03的条件下,正十二烯的转化率可达98.32%,2-LAB的选择性可达36.76%。离子液体和产物可形成易于分离的双液相,简化了催化剂与产物的分离操作。

| Abstract: | Different ionic liquids were prepared fromAlCl3 and [Bmim]C1 ,and effects of the different reaction conditions on the alkylation of benzene and 1-dodecene were investigated. The optimal reaction conditions were obtained. The experimental results show that when [BMIM]Cl-xAlCl3ionic liquid prepared when the molar ratio of AlCl3 to [Bmim] Cl is 2.0 is used as catalyst, reaction temperature is 25 ℃ and reaction time is 30 min and the molar ratio of benzene to 1-dodecene to catalyst is 5：1：0.03, conversion of 1-dodecene can reach to 98.32 % ,and selectivity of 2-LAB can reach to 36.76 %.The reaction system can form two phases, so the ionic liquid catalyst is easy to be separated from the product. |
