Abstract
Abstract Nitroso aryloxy quaternary ammonium compounds, such as tetra alkyl ammonium nitrosophenate, are new compositions of matter in which the presence of the nitroso substituent, which is oxidizable to NO2 or reducible to NII2 in appropriate media, enhances the known effectiveness of the component ammonium radicals in bactericidal, fungicidal, antiseptic and other biologically prophylatic roles and confers on the compound other beneficial properties such as rust inhibition. The invention further contemplates method for the in situ generation of amino and nitrite substituted quaternary ammonium compounds in liquid media.
