Abstract
The present disclosure generally relates to corrosion inhibitor compositions and methods of using the compositions to inhibit corrosion. The corrosion inhibitor compositions include glucamide-containing compounds. The compositions can effectively inhibit corrosion of various metallic surfaces. The metallic surfaces may be found in a pipeline, a downhole tubular, a casing, a tank, a separator, a processing unit, and/or a filter, for example. The compositions may also include additional components, such as solvents, biocides, and scavengers.
Claims19
A method of inhibiting corrosion of a metal surface in contact with a medium, comprising:
- adding an effective amount of a composition to the medium, wherein the composition comprises a glucamide-containing compound having a structure of Formula I, Formula II, an enantiomer thereof, and/or a diastereomer thereof,
- wherein R1 is selected from a saturated or unsaturated C1 to C50 alkyl group, a saturated or unsaturated C1 to C50 alkenyl group, a hydroxyl group, hydrogen, an amido group, a fatty amido group, a quaternary amine, an acid, a fatty alcohol, an ester, a heteroatom, a cyclic group, a non-cyclic group, an aromatic group, a non-aromatic group, a carbonyl group, ethylene oxide, propylene oxide, or butylene oxide;
- wherein R2 is selected from a saturated or unsaturated C1 to C50 alkyl group, a saturated or unsaturated C1 to C50 alkenyl group, a hydroxyl group, hydrogen, an amido group, a fatty amido group, a quaternary amine, an acid, a fatty alcohol, an ester, a heteroatom, a cyclic group, a non-cyclic group, an aromatic group, a non-aromatic group, a carbonyl group, ethylene oxide, propylene oxide, or butylene oxide;
- wherein R3 is selected from a saturated or unsaturated C1 to C50 alkyl group, a saturated or unsaturated C1 to C50 alkenyl group, a hydroxyl group, hydrogen, an amido group, a fatty amido group, a quaternary amine, an acid, a fatty alcohol, an ester, a heteroatom, a cyclic group, a non-cyclic group, an aromatic group, a non-aromatic group, a carbonyl group, ethylene oxide, propylene oxide, or butylene oxide;
- and
- wherein X is selected from chloride, bromide, iodide, sulphate, acetate, phosphate, or nitrate.
