The hydrolysis of 1‐chloro 2‐nitro ethane, chloro diphenyl methane and benzoyl chloride in dioxane‐water mixtures at 1–1000 at

Abstract

AbstractThe rate constants for the hydrolysis reactions of 1‐chloro 2‐nitro ethane, chloro diphenyl methane and benzoyl chloride in dioxane‐water mixtures were determined between 1 and 1000 at. The reaction of water with 1‐chloro 2‐nitro ethane, which is of the SN2 type, was studied at 70 °C in the solvent range of 9.8–49.3 weigth‐% water. The reaction of water with chloro diphenyl methane, which is of the SN1 type, was studied at 25 and 50 °C in the solvent range of 9.8–36.0 weight‐% water. The hydrolysis of benzoyl chloride, for which different mechanisms have been proposed, was studied at 25 °C in the solvent range of 4.3–29.3 weight‐% water. The volumes of activation for the total pressure range and the apparent molar volumes of the reactants for 1 at were determined and an interpretation of the volumes as functions of the solvent composition was attempted.
