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 aromatic ligands containing at least two hydroxy functional groups, or at least one amino and one hydroxy group, in the ortho position with respect to one another. The quinone compound is preferably added to these compositions in order to render the compositions compatible with chelating phosphonate scale control agents. The use of these compositions as oxygen scavengers in corrosive environments is also described.
