Abstract

1,201,334. Inhibiting corrosion. ALBRIGHT & WILSON (MFG.) Ltd. 12 Oct., 1967 [12 Oct., 1966; 12 June, 1967], Nos. 45653/66 and 27069/67. Heading C1C. The corrosion of metals in water systems using water which does not deposit a calcareous scale is inhibited by the inclusion in the water of certain phosphonic acids and salts thereof.
