Abstract

L'invention décrit des compositions d'inhibition de la corrosion, qui contiennent une hydrazine et un catalyseur. La composition contient une hydrazine, un complexe organométallique (produit de la réaction d'un hydroxyde cobalteux ou manganeux et d'un ou plusieurs coordinats, choisis parmi les dérivés aminés, substitues et non substitués, d'acides carboxyliques et de leurs sels) et, de préférence, une quinone (ajoutée afin de rendre la composition compatible avec les phosphonates, agents de chélation pour combattre la rouille). Les compositions peuvent servir à fixer ou éliminer l'oxygène dans des milieux corrosifs.
