The isomerization rate of aminosulfonic acids in anhydrous binary mixtures of sulfuric and acetic acids is lower than in aqueous sulfuric acid solutions but higher than in 100percent sulfuric acid.This is explained by the differences in the structure and activity of the proton carriers during desulfonation.The rate of transformation of the labile isomers into the meta isomers increases with increase in the acidity of the medium, and this is due to the increase in the resulfonation rate of the protonating molecules of the amines formed during the desulfonation of the aminosulfonic acids.The effect of mercuric sulfate on the isomeric transformations of aminosulfonic acids is explained by the mercuration of the protonated molecules of the amines, which takes place at higher rates than their sulfonation and leads to the formation of the meta-mercury derivatives of the amines.The latter are than converted into the m-aminosulfonic acids by the action of concentrated sulfuric acid.
