Kinetics of hydrolysis of aromatic mono- and disulfonyl chlorides

A continuous polarografic method of recording instantaneous concentrations of - SO2Cl groups in an aqueous acetic acid system containing CH3CO2Na has been elaborated.Ten model monosulfonyl chlorides underwent hydrolysis according to pseudo-first order kinetics (20percent H2O, 80percent v.v.CH3CO2H, 0.5 mol/dm3 CH3CO2Na).Plots of hydrolysis for seven disulfonyl dichlorides with different number of - CH3 groups have been determined.Pseudo-first order rate constants for two consecutive reactions of hydrolysis (k1 and k2) have been computed and the influence of -SO2Cl and -SO3- groups on the reactivity of the second group - SO2Cl has been discussed.The mechanism of nucleophilic substitution has also been discussed.
