Alkyl lactone-derived corrosion inhibitors
Disclosed are alkyl lactone-derived hydroxyamide and alkyl lactone-derived hydroxyester used in compositions and methods for inhibiting corrosion. The alkyl lactone-derived hydroxyamide and alkyl lactone-derived hydroxyester are reaction products of an alkyl lactone and an amine, and an alkyl lactone and an alcohol, respectively.
