HYDROLYSIS OF AROMATIC SULFONIC ACIDS UNDER THERMODYNAMIC CONTROL OF THE REACTION

Linear mathematical models which describe the hydrolysis of alkyl- and halobenzenesulfonyl acids under the conditions for their isomerization in sulfuric acid have been obtained by the method of mathematical experiment planning.The value of the effective rate constants of hydrolysis calculated according to the models for comparative conditions (150 deg C, 3 moles of 85percent sulfuric acid) were used to obtain the correlation between log kh and the ? constants of the substituents.The correlation corresponds the electrophilic nature of the hydrolysis process (ρ = -4.69).The strong influence of the electronic effects of the substituents on the rate of hydrolysis is an indication of the development of a considerable positive charge on the reaction center in the transition state.
