摘要:
                                Quaternary ammonium salts were synthesized on the basis of hexamethylenetetramine and piperylene hydrochloride. Conditions for the synthesis of mono-, di-, tri-, and tetraalkenylhexamethylenetetrammonium chlorides in aqueous solutions were optimized. The main physicochemical characteristics of the synthesized compounds were determined and the structures were established. The suppression of the growth of sulfate-reducing bacteria was studied.
