Onium Salts of Sulfur-Containing Oxyanions Resulting from Reaction of Sulfur(IV) Oxide with Aqueous Solutions of 1,2-Diamines and Morpholine

Abstract

Reaction products have been isolated from SO2–L–H2O–О2 systems (L = ethylenediamine, N,N,N',N'-tetramethylethylenediamine, piperazine, and morpholine) as onium salts [H3NCH2CH2NH3]SO4, [(CH3)2NHCH2CH2NH(CH3)2]SO4, [(CH3)2NHCH2CH2NH(CH3)2]S2O6 ⋅ H2O, [C4H8N2H4]SO3 ⋅ H2O, [C4H8N2H4]S2O6, [C4H8N2H4]SO4 ⋅ H2O, [O(C2H4)2NH2]2SO4 ⋅ H2O. The prepared compounds have been characterized by X-ray diffraction analysis, X-ray powder diffraction, IR and mass spectroscopy.
