ABSTRACT:
A method for inhibiting corrosion in an aqueous medium is disclosed. The method comprises incorporating into the medium an amount of a water-soluble corrosion inhibitor sufficient to inhibit corrosion. The corrosion inhibitor comprises an N-ethoxy, 2-substituted imidazoline, the N-ethoxy substituent having from one to about thirty ethoxy units and the 2-substituent being an unsaturated or polyunsaturated fatty chain of from about six to about thirty carbons. If the medium is sweet, the inhibitor further comprises a phosphate ester derived from a water-soluble oxyethylated, straight chain alcohol of from about two to about thirty carbons. Corrosion inhibitor compositions useful in such method are also disclosed.
