应用简单、洁净的固相合成方法合成了氯球(氯甲基聚苯乙烯)担载的1-6代聚酰胺-胺树状分子金属铜配合物,通过IR、ICP和XPS对配体和配合物的结构进行了表征,将此类配合物用作在无溶剂情况下分子氧氧化乙基苯的催化剂,研究了其催化性能,并探讨了反应温度、反应时间、催化剂用量、酸碱添加剂以及催化剂重复利用对反应的影响.研究结果表明此类配合物对乙基苯的氧化反应具有一定的催化活性,反应以苯甲酮,1-苯基乙醇,苯偶姻为主要产物.此催化体系使用环境友好的氧化剂,催化剂制备方法简单、催化剂在多次重复利用后活性没有明显降低,可回收和重复利用.
A simple and clean solid phase synthesis method was used to synthesize the dendrimers of 1-6-polyamidoamine dendrimer loaded with chloro-methylpolysiloxane (CPM) The structure of the complex was characterized. The complex was used as a catalyst for the molecular oxygen oxidation of ethylbenzene in the absence of solvent. The catalytic performance was studied. The effects of reaction temperature, reaction time, amount of catalyst, As well as the influence of the catalyst recycle on the reaction.The results show that these complexes have certain catalytic activity for the oxidation of ethylbenzene, the main reaction products are benzophenone, 1-phenylethanol and benzoin. The system uses environmentally friendly oxidant, the catalyst preparation method is simple, the catalyst after repeated use of no significant reduction in activity, recyclable and reusable.
