发明名称 Corrosion inhibitors of copper resistant to halogens
摘要 <p>Non-halogen substituted, nitrogen containing, aromatic compounds are disclosed which are effective copper corrosion inhibitors in aqueous systems being treated with a halogen biocide. The materials of the present invention exhibit copper corrosion inhibition comparable to tolyltriazole in the absence of halogen, copper corrosion rates of less than about 2.5 mills per year in aqueous systems where halogen is present; and do not exhibit a detrimental effect on halogen demand in an aqueous system being treated.</p>
