Abstract
Corrosion inhibiting compositions are described which contain a hydrazine compound, an organometallic complex and a quinone compound. The organometallic complex is the reaction product of a cobaltous, manganous, or cupric inorganic salt and one or more aromatic ligands containing at least two hydroxy or two amino functional groups, or at least one amino and one hydroxy group, in the ortho position with respect to one another. The quinone compound is one which renders the composition compatible with chelating phosphonate scale control agents. The use of these compositions as oxygen scavengers in corrosive environments is also described.
