Abstract The concentrations of the uncharged and anionic forms of m-and p-aminobenzoic acids participating in arylsulfonation of the acids with m-and p-nitrobenzenesulfonyl chlorides in the system water-2-propanol at 298 K at various water contents and pHs were estimated. The resulting data were used to estimate the rate constants for the reactions of the above forms with nitrobenzenesulfonyl chlorides, based on experimental kinetic data.
