Alkoxy benzotriazoles compositions and use the than copper and copper alloy corrosion inhibitors

摘要

An alkoxybenzotriazole, in combination with mercaptobenzothiazole, tolyltriazole, benzotriazole, a substituted benzotriazole and/or 1-phenyl- 5-mercaptotetrazole, is used to inhibit the corrosion of metallic surfaces, particularly copper surfaces, in contact with an aqueous system. Systems and compositions are also claimed.
