    摘要： A method and compounds for inhibiting the formation of scale, e.g., barium scale, and controlling corrosion is disclosed. The method is particularly effective at inhibiting or preventing corrosion of ferrous-based metals in contact with the aqueous systems such as cooling water systems. The method comprises introducing into the aqueous system a compound of the general formula: ##STR1## wherein R is hydrogen, alkyl, aryl, substituted alkyl or substituted aryl; R' and R" are each independently hydrogen, C.sub.1-4 alkyl or C.sub.1-4 substituted alkyl; Z is O, S, NH or NR, where R is as described above; n is a positive integer greater than 1; f is a positive integer; and M is hydrogen, a water soluble cation (e.g., NH.sub.4.sup.+, alkali metal), or a C.sub.1-3 alkyl group.
