Abstract

The kinetics of chlorination of acetone'(AC), ethyl methyl ketone (EMK), ethyl phenyl ketone (EPK), methyl isobutyl ketone (MIK), diethyl ketone (DEK), acetophenone (A), 3', 4'-dirnethoxy acetophenone (DMA) and p-hydroxy acetophenone (HA) by sodium N-chlorobenzene sulphonamide (Chloramine-B or CAB) in hydrochloric and perchloric acid media has been carried out at 30 C. The effect of [H+] and [CI-], variation of ionic strength and dielectric constant to the medium on the rate of reaction has been studied, Addition of the reaction product, benzene sulphonamide had no effect on the rate of chlorination. Thermodynamic parameters have been evaluated by studying the kinetics at various temperatures. Suitable mechanisms have been proposed in consistency withthe kinetic results.
