Kinetics and mechanism of the acid hydrolysis of mono-5- chloro, 2-methylaniline phosphate ester


Amit Chaudhary

The acid hydrolysis of mono-5-chloro, 2- methylaniline phosphate in the acid range 0.1 to 6.0 M HCl at 80 + 0.5 0C has been performed in water. The concentration of monoester in all kinetic runs used was 5.0 × 10–4 moldm–3. The inorganic phosphate obtained in overall hydrolysis has been estimated colorimetrically by Allen’s modified method. The first order rate coefficients have been calculated using integrated form of the corresponding rate equation. rnKe = KH+. CH+. exp.Conjugate acid, neutral, mononegative and dinegative species have been found to be reactive and contribute to the overall rates, but in this discussion only conjugate acid and neutral species are given. The rate coefficients estimated by above equation are fairly in good agreement with the experimentally observed rates. Factors such as hydrogen ion concentration, ionic strength, temperature, solvent, substrate concentration effects etc., have been studied to find the participation of water molecules, bond fission and molecularity of the reaction. Probable mechanism of the acid hydrolysis of mono-5-chloro,2-methyl aniline phosphate via different reactive species has been suggested on the basis of kinetic rate data and iso kinetic relationship.rn
