Abstract

Sulfosalicylate d'hydrazine répondant à la formule : [NH2NH2]a[C6H3(COOH)(SO3H)(OH)]b dans laquelle a=1, et 1<b<2, et un procédé pour sa préparation, dans lequel on fait réagir de l'acide sulfosalicylique et/ou son hydrate avec de l'hydrazine et/ou son hydrate, selon un rapport molaire de 1:1 à 3:1 dans un milieu aqueux à une température comprise entre 5 et 60 degrés C. Le sulfosalicylate d'hydrazine peut être mis en oeuvre pour la stabilisation à effet antioxydant de composés stanneux, en particulier pour la coloration électrolytique d'aluminium ou d'alliages d'aluminium.
