A method for reducing the toxicity of onium compounds, such as ammonium
compounds and phosphonium compounds, by the use of certain additives is
described. Suitable additives include, but are not necessarily limited to,
carboxylic acids (e.g. naphthenic acids), sulfonic acids, organophosphonic
acids, phenolic compounds, ether sulfates, phosphoric acid esters,
sulfonated fatty acids, sulfated fatty acids, oligocarboxylic acids, and
mixtures thereof, and alkali metal salts of these compounds and amine
salts of these compounds.
Um método para reduzir o toxicity de compostos do onium, tais como compostos do ammonium e compostos do phosphonium, pelo uso de determinados aditivos é descrito. Os aditivos apropriados incluem, mas necessariamente não são limitados a, ácidos carboxylic (por exemplo ácidos naphthenic), ácidos sulfonic, ácidos organophosphonic, compostos phenolic, sulfates do ether, esters do ácido phosphoric, não sulfonated ácidos fatty, ácidos fatty sulfated, ácidos oligocarboxylic, e misturas disso, e sais alcalinos destes compostos e sais do amine destes compostos.
