Complexing of Sulfur(IV) Oxide with Hexamethylenetetramine and Hexamethylenediamine in Aqueous Solutions

Abstract

Interaction in the sulfur(IV) oxide–hexamethylenetetramine (hexamethylenediamine)–water systems was studied by pH-, redox-, and conductometric titration techniques. The structure and stability of the resulting molecular and ionic complexes were examined in relation to the nature and concentration of the components in solution, as well as to temperature.
