摘要： 以苯乙烯系7 3 2型阳离子交换树脂为载体, 通过离子交换络合无水 A l C l 3, 制备 A l3+/阳离子交换树脂催化剂, 并考察了制备 A l3+/阳离子交换树脂催化的工艺条件。实验结果表明, 7 3 2型阳离子交换树脂减压干燥1 2h, 以四氯化碳为溶剂, 交换温度7 2℃, 无水 A l C l 3 与7 3 2型阳离子交换树脂质量比为1. 1∶1, 交换时间为1 0h,后处理采用蒸馏水 - 乙醇( 质量分数9 5%) - 蒸馏水洗, Al3+的负载量达到2. 2 9%。将 Al3+/阳离子交换树脂催化剂用于乙烯裂解副产C 9  馏分催化聚合反应。在反应温度为5 0℃, 反应时间6h, 催化剂中 Al3+质量分数为2%, 得到的聚合物通过红外分析结构, 结果表明 A l 3+/阳离子交换树脂固体催化剂在多烯烃系统里具有良好的催化效果。使用树脂固体催化剂催化聚合多烯烃, 省去脱除催化剂过程, 不产生反应系统的洗脱废液。

Abstract: Al3+/cation exchange resin catalyst was prepared by ion exchange complex, with commercial 732 cation exchange resin as carrier and aluminium trichloride as ion exchangers. The process conditions of the preparation of Al3+/cation exchange resin catalyst were investigated. The experimental results showed that the quality of supported on Al3+ can be up to 2.29% when the decompression drying time of 732 cation exchange resin was 12 h, the solvent was carbon tetrachloride, exchange temperature was 72 ℃, the mass ratio of aluminium trichloride and 732 cation exchange resin was 1∶1, exchange time was 10 h and postprocessing was in turn with the distilled water and ethanol (95%). Al3+/cation exchange resin catalyst was used to catalyze the polymerization of ethylene cracking fraction（C 9 ）.Al3+/cation exchange resin had good catalytic effect in the mixed olefin system when the reaction occurred at 50 ℃ for 6 h with catalyst dosage 2%( according to the quality of Al3+ content meter). Structure of polymer was verified by infrared spectroscopy.
