Abstract

1374270 Treating water CIBA-GEIGY AG 7 Dec 1972 [10 Dec 1971] 57413/71 Heading C1C [Also in Division C7] A corrosion-inhibiting composition comprises 2À5 to 80 wt. per cent Zn<++> and 97À5 to 20% hydrolysed polymaleic anhydride. The composition is added to aqueous media in contact with metal such as steel, Cu, brass, or Al to inhibit corrosion and scaling; since polymerized maleic anhydride readily hydrolyses in aqueous media, the term “hydrolysed polymaleic anhydride” above includes both pre-hydrolysed polymaleic anhydride and also polymerized maleic anhydride hydrolysable on addition to water. The M.W. of the polymer may be 300- 5000; the source of Zn<++> may be the borate, chloride, nitrate or sulphate, and there may be added to the composition benzotriazole, bisbenzotriazole or their Cu-deactivating derivatives as Cu corrosion inhibitors, silicate to control attack on Al, or iron-corrosion inhibitors such as chromium, nitrite, or amines; 0À1-500 p.p.m. of composition are added to the aqueous system.
