摘要：选用AlCl3/乙醇络合催化体系对1-癸烯齐聚反应进行研究。采用GC-MS分析方法测定产物组成,考察温度对聚合速率的影响,通过计算得到聚合表观活化能,并对1-癸烯齐聚动力学行为进行理论研究和分析,建立了排除扩散影响的简化动力学方程。结果表明：AlCl3/乙醇络合催化剂催化的1-癸烯齐聚反应的表观活化能为4.98kJ/mol;该反应为阳离子聚合过程,在AlCl3摩尔分数为2%、乙醇与AlCl3的摩尔比为0.9、反应温度为0-100℃、反应时间为3h、搅拌速率为600r/min的条件下,反应所得的齐聚产物主要为1-癸烯的三聚体和四聚体,且随着反应温度的升高,生成的二聚体、三聚体含量升高,四聚体、五聚体含量下降。
The oligomerization of 1-decene was studied with AlCl3-ethanol complex as catalyst.The products were analyzed by GC-MS to investigate the effect of reaction temperature on the reaction rate.The simplified kinetic equation was established,and the apparent activation energy was obtained by calculating the conversion of 1-decene.The results show that 1-decene oligomerization catalyzed by AlCl3-ethanol complex is a cationic reaction process with apparent activation energy of 4.98kJ/mol.At AlCl3 mole ratio of 2%,ethanol/AlCl3 molar ratio of 0.9,reaction temperature in the range of 0—100 ℃,reaction time of 3hand stirring speed of 600r/min,the products of oligomerization are mainly trimers and tetramers.As the reaction temperature increase,the yield of dimmers and trimers increases,and the yield of tetramers and pentamer decreases.
