The reaction products formed in the SO2–L–H2O–O2 systems (L is n-propylamine, n-butylamine, tert-butylamine, n-heptylamine, n-octylamine, aniline) were isolated and identified as “onium” salts [n-C3H7NH3]2SO4, [n-C4H9NH3]2SO4, [t-C4H9NH3]2SO4, [n-C7H15NH3]3SO4(HSO4), [n-C8H17NH3]3SO4(HSO4), and [C6H5NH3]2SO4. The products were characterized by elemental analysis, IR and Raman spectroscopy, mass spectrometry, and thermogravimetry.

Di-ortho ring substituted arylammonium sulfates (Di-o-RSAS) have been prepared from the corresponding arylamines by treatment with conc. H2SO4 and characterized by elemental, gravimetric and spectral analyses. These sulfates yield the corresponding ring substituted aminobenzenesulfonic acids (RSABSA) when subjected to thermal energy. Non-isothermal gravimetric studies on di-o-RSAS support the formation of RSABSA. It is observed that most of the salts undergo transformation to acid in solid state via proton transfer reaction prior to sulfonation.
