| titleOfInvention | Halogen resistant corrosion inhibitors |
| abstract | A method of inhibiting corrosion of copper surfaces contacted by an aqueous system being treated with an oxidizing halogen biocide comprises adding to the aqueous system a corrosion inhibitor. The corrosion inhibitor comprises a non-halogenated, substituted benzotriazole selected from: 5,6-dimethyl- benzotriazole; 5,6-diphenylbenzotriazole; 5-benzoyl- benzotriazole; 5-benzyl-benzotriazole and 5-phenyl- benzotriazole which: a) exhibit an 18 hour average copper corrosion rate of less than 0.3 mpy (mills per year) in the aqueous system in the absence of oxidizing halogen biocide treatment of the aqueous system; b) exhibit a 22 hour average copper corrosion rate of less than 2.5 mpy in the aqueous system after treatment of the aqueous system with 5 ppm of oxidizing halogen biocide; c) exhibit a free chlorine concentration, in the aqueous system, of at least 4.0 ppm at 19 hours after the aqueous system is treated with 5 ppm chlorine; and d) exhibit a free chlorine concentration, in the aqueous system, of at least 2.0 ppm at 40 hours after the aqueous system is treated with 5 ppm chlorine. |
