以苯乙烯系732型阳离子交换树脂为载体,通过离子交换络合无水 AlCl3,制备 Al3+/阳离子交换树脂催化剂,并考察了制备 Al3+/阳离子交换树脂催化的工艺条件。实验结果表明,732型阳离子交换树脂减压干燥12 h,以四氯化碳为溶剂,交换温度72℃,无水 AlCl3与732型阳离子交换树脂质量比为1.1∶1,交换时间为10 h,后处理采用蒸馏水-乙醇(质量分数95%)-蒸馏水洗,Al3+的负载量达到2.29%。将 Al3+/阳离子交换树脂催化剂用于乙烯裂解副产C9馏分催化聚合反应。在反应温度为50℃,反应时间6 h,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 Al3+/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。

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(C9 ).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.
