Abstract

Abstract:

The dinuclear copper complexe was synthesized and characterized. The macrocyclic copper complexe was immobilized on SAPO-5 molecular sieve, functionalized SAPO-5 molecular sieve by γ-aminopropyl. The sample was characterized by BET, IR and UV-vis spectroscopies, XRD, ICP-AES and TG/DTA techniques,and its structure still remained intact. The catalytic properties of the prepared catalyst were studied by the cyclohexane oxidation with H2O2 as an oxidant. The catalytic results show that the catalyst has the better activity and stability in cyclohexane oxidation. Amongst all the solvents ,cyclohexane conversion is the highest (55.1%) when acetonitrile was used as solvent. The influences of time and temperature on cyclohexane conversion are also further investigated. The considerable reactive condition should be reaction time (10～12 h), reaction temperature (80～90 ℃) respectively.

摘要： 合成了一种铜双核大环金属配合物。采用浸渍法将双核配合物固载在分子筛SAPO-5中制得负载催化材料，其中磷酸铝分子筛SAPO-5采用三甲氧基氨丙基硅烷将表面官能化。BET，IR，UV-Vis，XRD，ICP-AES和TG/DTA表征结果表明配合物被固载后，其结构仍保持完整。以环己烷氧化为探征反应，考察了负载催化材料的催化性能。结果表明该负载催化剂具有较高的活性，当选用乙腈做溶剂时，环己烷的转化率高达55 .1%。该负载催化剂在环己烷液相反应中的最佳反应条件为：反应时间在10～12 h，反应温度在80～90℃。
