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).
用于抑制与水性介质接触的金属表面腐蚀的组合物和方法,例如开放循环冷却水系统中的铜、铜合金和钢表面。在某些实施例中,将带有阴离子取代基与三唑的氮原子结合的芳香族三唑(ANST)用作腐蚀抑制剂。在其他实施例中,腐蚀抑制剂是芳香族三唑和醛的反应产物(ATA)。
