| 摘 要： | 聚乙烯吡咯烷酮（PVP）络合Pd^2＋后，负载于聚乙二醇（PEG）功能化的Al2O3柱支撑后的膨润土（Al-PRT）上，制备了催化剂PVP-PdCl2／Al-PRT-PEG，并用于催化不溶于水的对氯甲苯水相脱氯．实验表明该催化剂呈现出较高的脱氯活性和重复使用功能．用IR，XRD等手段表征了Al-PRT，并探讨了催化剂各组分在催化脱氯反应中的作用．

| Abstract: | A novel catalyst PVP-PdCl_2/Al-PRT-PEG was prepared through supporting the PVP(polyvinglpyrrolidone)-archored Pd~(2+) on Al-PRT(Al_2O_3-pillared bentonite) function-allied by PEG(polyethylene glycol).It has shown better dehalogenetion activity and reusability for catalyzing dechlorination of insolvable p-chlorotulunce in agueous system.The Al-PRT has been characterized by IR,XRD.The effect of each catalyst's composition in dechlorination reaction is discussed. |
