Investigations of the kinetic study of the hydrolysis of mono-2, 6-di-methylphenyl phosphate has been carried out in 0.1 to 6.0 mol.dm3.HCL and in buffers from 1.24 to 7.46 pH at 97 ± 0.5°C in water. The monoester has been found to be hydrolyses by conjugate acid, mononegative, neutral and dinegative species. Bond fission, molecularity and order of reaction have been supported by Arrhenius parameters, Zucker Hammett hypothesis, concentration, solvent effect etc., study of the reaction and dioxane-water mixture suggested the nature of transition state in which charges are developed due to the bimolecular attack of water molecule. Comparative isokinetic rate data of similarly substituted other phosphate monoesters, whose mechanism is known, supported P-0 bond fission.
