对位单取代缬氨酸四苯基卟啉锰催化氧化烃类的研究

Studies of Hydrocarbons Oxidation Catalyzed by Para monosubstituted Valine Tetraphenyl porphyrin manganese

测定了对位单取代缬氨酸四苯基卟啉锰（简记为ＭｎＬＶａｌＣｌ）与锌粉、乙酸和咪唑组成的氧化模拟体系催化氧化烯烃和烷烃的吸氧动力学曲线；研究了不同助催化剂对体系催化活性的影响。结果表明，该体系催化各类烯烃的环氧化产物收率（Ｚｎ％）由高到低的顺序为：环已烯＞１－癸烯＞丙烯酸甲酯＞烯丙基丙酮，用吡啶（Ｐｙ）代替米唑（Ｉｍ）作助催化剂可明显提高体系的吸氧速度。

The oxygen uptake dynamical cure of oxidation minetic system for hydrocarbons oxidation is measured in this paper. The system consists of MnL Val Cl,Im,Zn and CH 3COOH. The effects of the different cocatalysts on the catalytic activity in the system are also studied. The results show that the oxidation yield of the system diminish as follows: Cyclohexene,1 decene, methylpropenoicate and allylaceton, and the highest uptake oxygen rate will be increased by substituting Pyridine for imidazole.
