()
摘要:
本文结合meso-四-(4-甲氧苯基)卟啉与金属离子的显色反应,对非水溶性卟啉显色体系中非离子型表面活性剂增溶增敏机理和辅助络合剂的催化作用机理进行了探讨,用“氢键增溶模型”、“催化场模型”和“过渡络合物模型”对上述增溶、增敏和助络催化作用分别进行了解释。

Mcchanisms of Solubilization and Sensitization Caused by Surfactants and Assistant Complexant in Color Systems of Metal Ions with Water-insoluble Porphyrin
()
Abstract:
The mechanisms of both solubilization and sensitization of non-ionic surfactant and the assis-tant complexant catalysis in the color system of metal ions with meso-tetrakis-(4-methoxyphenyl)-porphyrin were studied. The Model of Hydrogen Bond Solubilization , the Modelof Catalysis Field and the Model of Transitional Complex respctively were developed and usedfor the explanation of the above mechanisms.The theory reported here can serve as guidance ofselecting assistants and improving sensitivity and selectivity in metal- porphyrin color reaction.
Key words:  Miceller solubilization,Miceller sensitization,Reaction mechanism,Porphyrin,Surfactant
