Abstract

Abstract Thirteen monosubstituted arylsulphonamides (XC 6 H 4 SO 2 NH 2) and two 3, 4- disubstituted arylsulphonamides (X 2 C 6 H 3 SO 2 NH 2) have been synthetized and their dissociation constants have been measured by potentiometric titration in water, methanol, and ethanol. The Hammett substitution dependences have been calculated for all the media, and changes in the reaction constants due to transition from water to alcohols are ...
