Kinetics of the transesterification reaction between phenyl carbanilate and 1 -octanol

Abstract

The kinetics of the transesterification reaction between phenyl carbanilate and 1-octanol were studied. The reaction was carried out in 1, 2-dimethoxy ethane as the solvent at a temperature of 100°. Two mechanisms for the transesterification were possible; a two-step mechanism involving dissociation to isocyanate or a bimolecular displacement involving a carbonyl addition intermediate. The rate constants for both the above mechanisms were calculated from the experimental data. Neither of the above mechanisms alone could account for the experimental data and a dual mechanism was postulated.
