Title (EN) HALOGEN RESISTANT CORROSION INHIBITORS
(FR) INHIBITEURS DE CORROSION RESISTANTS A L'HALOGENE
Abstract: front page image
(EN)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.
(FR)L'invention concerne des composés aromatiques contenant de l'azote substitués par un non halogène, qui sont efficaces comme inhibiteurs de corrosion dans des systèmes aqueux traités avec des agents biocides à l'halogène. Ces composés produisent une inhibition de la corrosion du cuivre comparable au tolyltriazole en l'absence d'halogène, des taux de corrosion du cuivre inférieurs à environ 2,5 mils/année dans des système aqueux où l'halogène est présent; et ne produisent pas un effet nuisible sur les exigences en halogène d'un système aqueux en cours de traitement.
