| titleOfInvention | Scale and corrosion inhibition for cooling water systems |
| abstract | 1423920 Inhibiting scale and corrosion NALCO CHEMICAL CO 22 April 1974 [31 July 1973] 17541/74 Heading C7E A corrosion and scale inhibiting composition for addition to water in contact with metal comprises (1) 30-50 wt per cent of an alkoxylated polyol phosphate ester (2) 2-25% of a soluble Zn compound (calculated as ZnCl 2 ) (3) 5-25% of tannin (which term includes lignin) and (4) 30-10% of water, wherein said polyol ester is R<SP>1</SP>(OR)y where R<SP>1</SP>=an aliphatic C 1 -C 6 radical, y = 2-5 and R is (A) (Alk O) n H or (B) -PO 3 H 2, n = 1-30 and Alk O is an ethylene oxide, a propylene oxide or a butylene oxide, at least one R being (B). Compound (2) may be ZnO or ZnCl 2 , and the tannin may be a catechol tannin such as cutch, quebracho, hemlock, larch or gambier, or a pyrogallol tannin such as gallnut, sumac, myrobalans, chestnut, valonia or dividivi, or a synthetic tannin. After start-up at e.g. 150 ppm, 30-150 ppm of the composition are maintained in the water, which may have pH 8-8.6, to inhibit corrosion of iron. |
