ABSTRACT:
Corrosion inhibiting compositions are described which contain a hydrazine compound and an organometallic complex. The organometallic complex is the reaction product of a cobaltous, manganous, or cupric inorganic salt and one or more ortho aromatic ligands containing at least two hydroxy or two amino functional groups or at least one amino and one hydroxy group. The use of these compositions as oxygen scavengers in corrosive environments is also described.
