Abstract

The invention relates to a method for producing hydroxylammonium salts by means of catalytic reduction of nitrogen monoxide with hydrogen in the presence of an acid and a hydrogenating catalyst, whereby the nitrogen monoxide is purified before the catalytic reduction by at least one treatment with porous oxides based on silicon and/or aluminium or with activated carbon. 8 claims
