Investigation of reaction of arylsulfochlorides with diethylenetriamine shows that independently of their molar ratio always mono- and disulfides are obtained. With increasing of quantity of amine the yield of monosulfamide rises till 43%. The further increase does not greatly influence on the yield of monosulfamides. It was shown that monosulfamides are easily changed into quaternary ammonium salts. During investigation of synthesized compounds as antimicrobial additives, their high efficiency was revealed
