【摘要】本文合成了疏水性高氯酸二水 (四胺 )合钴 (Ⅲ )配合物 ,研究了它与非离子表面活性剂Brij35形成的金属胶束催化二 (对硝基苯酚 )磷酸二酯水解的动力学及其机理。结果表明此金属胶束对磷酸二酯水解的速率大约提高 10 4 倍 ,这主要是由于表面活性剂胶束的pH效应和浓聚效应所致 ,暗示着顺式二水类配合物形成的金属胶束是一个潜在的磷酸二酯水解剪切的催化剂更多还原

【Abstract】 In this paper,hydrophobic diaquo(tetraamine) cobalt(Ⅲ) complex was synthesized and characterized,and the hydrolysis of two (n nitrophenyl) phosphate diester catalyzed by the metallomicelle made up of the complex and non ionsurfactant Brij35 was investigated kinetically.The results showed that the rate for the hydrolysis of phosphate diester increased by ca.10 4 folds due to the existence of the metallomicelle,which was caused by the pH effect and the concentration effect of surfactant micelle indicating that the metallomicelle made up of cis diaquo base metal complex is a potential catalyst for the hydrohytic cleavage of phosphate diester.更多还原
