Abstract
This invention relates to a corrosion inhibiting composition comprising (a) an aliphatic amine, (b) an azole selected from the group consisting of (1) tolyltriazole, (2) benzotriazole, and (3) mixtures thereof, and (c) a benzoate. The compositions are particularly useful in inhibiting the corrosion of metal equipment, particularly equipment made from cast iron and aluminum, and more particularly, engine blocks that have been subjected to water flushing. The invention also relates to a process for inhibiting corrosion, particularly the vapor phase corrosion of metal equipment.
