The products of SO2 interaction with aqueous solutions of methylamine, benzylamines, 1,2-diamines and morpholine

Abstract

The new method of preparation of sulphur oxoanions “onium” salts via interaction in the SO2–L–H2O–O2 systems (L is methylamine, benzylamines, 1,2-diamines, and morpholine) has been developed. “Onium” sulfates have been obtained from methylamine, benzylamine, α-phenylethylamine, N,N-dimethylbenzylamine, dibenzylamine, 1,2-ethylenenediamine, morpholine, N,N,N’,N’-tetramethylethylenediamine; sulphites monohydrates – from piperazine and N-(hydroxyethyl)ethylenediamine; dithionate – from piperazine and N,N,N’,N’-tetramethylethylenediamine. The compounds were characterized by elemental analysis, X-ray diffraction, IR, Raman spectroscopy, mass spectrometry, and differential thermal analysis.
