Abstract
Kinetic study of acid catalyzed hydrolysis of di-4-chloro, 3-methyl phenyl phosphate was studied in the acid region from 0.1 to 6.0 mol.dm-3 hydrochloric acid at 97 
0.50C in 20% dioxane- water mixture. The rate of reaction increase with increase in hydrochloric acid molarity upto 4.0 mol.dm-3 HCl which was largely contributed by the conjugate acid species. Rate data at constant ionic strength was used to identify the reactive species as to determine the theoretical rates. Hydrolysis of di-ester via conjugate acid species was assigned the biomolecular behavior of the reaction on the basis of Arrhenius parameters. Solvent effect on hydrolytic reaction was found to indicate the formation of a transition state in which charge dispersion occurs. The first order rate coefficient have been calculated by using integrated form of corresponding rate equation.
