利用作者合成的ET(30)染料,测定了85%(V/V)1,4-二氧六环+水+LiClO4,75%(V/V)1,4-二氧六环+水+LiClO4,80%(V/V)乙醇+水+LiClO4,乙醇+Et4NCl溶液的ET(30)值,考察了ET(30)值与一些溶剂解化学反应动力学数据间的关系.结果表明:一些溶剂解反应的速率常数与溶剂的ET(30)值有线性关系.本文从反应机理和溶液中的优先溶剂化作用的角度对这种现象进行了解释和说明.
Using the ET (30) dye synthesized by the author, the effects of 85% (V / V) 1,4-dioxane + water + LiClO4, 75% The relationship between the ET (30) value and some kinetic data of solvent-based chemical reactions was investigated by the ET (30) values of 80% (V / V) ethanol + water + LiClO4 and ethanol + Et4NCl solution. The rate constants of the solvolysis reaction have a linear relationship with the solvent ET (30) .This phenomenon is explained and explained from the reaction mechanism and the preferential solvation in solution.
