Title (EN) NITROGEN SUBSTITUTED AROMATIC TRIAZOLES AS CORROSION CONTROL AGENTS
(FR) TRIAZOLES AROMATIQUES SUBSTITUÉS PAR DE L'AZOTE EN TANT QU'AGENTS DE RÉGULATION DE CORROSION
Abstract: front page image
(EN)Compositions and methods for inhibiting corrosion of metallic surfaces in contact with an aqueous medium such as copper, copper alloy, and steel surfaces of an open recirculating cooling water system. In certain embodiments, an aromatic triazole having an anionic substituent bonded to a nitrogen atom of the triazole (ANST) is used as the corrosion inhibitor. In other embodiments, the corrosion inhibitor is a reaction product of an aromatic triazole and an aldehyde (ATA).
(FR)La présente invention concerne des compositions et des procédés pour inhiber la corrosion de surfaces métalliques en contact avec un milieu aqueux tel que le cuivre, un alliage de cuivre et des surfaces en acier d'un système d'eau de refroidissement à recirculation ouvert. Dans certains modes de réalisation, un triazole aromatique ayant un substituant anionique lié à un atome d'azote du triazole (ANST) est utilisé comme inhibiteur de corrosion. Dans d'autres modes de réalisation, l'inhibiteur de corrosion est un produit de réaction d'un triazole aromatique et d'un aldéhyde (ATA).
