摘要

磷酸酯的水解是最基本的化学生化反应之一。在4种不同温度下,研究了不同组成(0-40% v/v)的质子溶剂和非质子溶剂对单- 3,5 -二甲基苯胺磷酸水解的溶剂动力学效应。反应速率随溶剂比例的增加而增加。已对激活参数(Ea, ΔH≠,ΔG≠,-ΔS≠)进行了评估。从溶剂-溶质相互作用、介质过渡态的溶剂等方面说明了这些参数的意义。

Kinetic Study of Solvent Effect on the Hydrolysis of Mono-3, 5-Dimethylaniline Phosphate
The hydrolysis of phosphate esters is one of the most fundamental chemical and biochemical reaction. The kinetic solvent effect on the hydrolysis of mono-3, 5-dimethylaniline phosphate has been studied in aqueous mixtures of varying compositions (0-40% v/v) of some protic and aprotic solvents at four different temperatures. The rate of reactions increases with increasing proportion of solvents. Activation parameters (Ea, ΔH≠, ΔG≠, -ΔS≠) have been evaluated. The significance of these parameters have been explained on the basis of solvent-solute interaction, solvent of the transition state of the medium.
