Abstract

M. K. Singh

Kinetic study of Tri-2,5-dichloro aniline phosphate has been made in acid region (0.1 to 7.0 mol dm-3 HCl) at 80oC. Acid log rate profile has a rate maximum at 4.0 mol dm-3. Ionic strength data upto 3.0 m requires participation of conjugate acid species and to determine theoretical rates. Computed ionic strength data support this,since the estimated rates in the acid medium closely agree with those experimentally observed.PH,Salt, temperature.solvent, solvent-isotope,substrate concentration effects etc. have been studied.Bimolecular behaviour has been decided by the Arrhenius parameters and analysis of molecularity data. The triesters involves P-N bond fission which is strengthened by comparative kinetic data.
