The rate of benzoic acid catalyzed mutarotation reaction of N-(p-chlorophenyl)-B-D-glucopyranosylamine has been studied in the presence of LiCl, NaCL, KCl,RbCl, CsCl, NH4Cl and (CH3)4NCl in methanol and in methanolic benzoate buffer solutions, at 25oC. The effect of the ionic strength on the reaction, catalyzed by hydrogen ions and benzoic acid molecules, has been discussed. No specific intractions brtween the alkali metal ions and the reactant have been observed. Logarithms of the rate constants of the mutarotation reaction have been found to be lineary related to the dissociation constants of the alkali matal chlorides in methanol.
