Oligomers prepared by the reaction of an alpha , beta -ethylenically unsaturated aldehyde with organic amines are thermally rearranged to give a more thermally stable product having labile amino hydrogens available for further reaction. The thermally rearranged oligomers by themselves or after reaction with a carboxylic acid, organic halide or an epoxide containing compound are useful as corrosion inhibitors. These corrosion inhibitors prevent the corrosion of metal caused upon exposure to corrosion of metal caused upon exposure to corrosive oil and gas well fluids. |
