Patent ·
OSTI ID:6371807

A composition is provided which, when applied to a metal surface, forms a corrosion-inhibiting film thereon. The composition comprises an amine, a hydrocarbon or alcohol diluent and carbon dioxide. The composition can be prepared by pressuring carbon dioxide gas into a solution of the amine. The composition is particularly useful in the treatment of down-well metal surfaces in oil and gas wells to inhibit the corrosion of the metal.
