ABSTRACT:
Corrosion inhibiting compositions are described which contain a hydrazine compound, an organometallic complex, and, preferably, a quinone compound. The organometallic complex is the reaction product of a cobaltous or manganous hydroxide and one or more organic ligands selected from the group consisting of unsubstituted and substituted amino derivatives of carboxylic acids and salts thereof. The quinone compound is preferably added to these compositions in order to render them compatible with chelating phosphonate scale control agents. The use of these compositions as oxygen scavengers in corrosive environments is also described.
