Abstract
Hexamethylene - bis - (trimethylammonium chloride) is prepared by directly quaternizing N,N,N1,N1 - tetramethylhexamethylenediamine by dissolving it in an organic solvent for the quaternary salt, e.g. n-propanol or ethanol, heating up to about 50 DEG C., adding methyl chloride and allowing the solution to reflux until the pH drops to 7 or less and crystallizing.
