ABSTRACT:
The invention is an improved process for inhibiting corrosion of metals in water conducting systems. It comprises employing in combination a compound of manganese together with organic aminoalkylenephosphonic acid derivatives to the water in such systems. These amine derivative compounds may also contain other functional groups, e.g., carboxylates, quaternary amines, hydroxyalkyl groups and the like.
