Maleated fatty imidazoline derivatives for corrosion inhibitors

Abstract

Compositions and methods for inhibiting corrosion of metal surfaces are disclosed herein. Also disclosed are methods of manufacturing the corrosion inhibitors compositions. The corrosion inhibitor compositions include a reaction product of maleated fatty imidazoline formed from a fatty acid, e.g., maleated tall oil fatty acid and/or a maleated soya acid, with one or more amines. The reaction product can be further reacted with one or more of acrylic acid or acetic acid to form derivatives of a maleated fatty imidazoline acrylate compound or a maleated fatty imidazoline acetate compound, respectively.
