Method of preservation of aqueous systems by addition to said systems of quaternary ammonium salts of hexamethylenetetramine

摘要

Quaternary ammonium salts formed by the reaction of hexamethylenetetramine with carboxylic acids and esters, amides and nitriles substituted in the alpha position by chlorine or bromine are preservatives for aqueous solutions, emulsions, and suspensions which are susceptible to microbiological degradation.
