1. A method of inhibiting corrosion of a metallic surface in contact with a corrosive fluid, the method comprising adding to the corrosive fluid an ionic liquid having the formula:
[Cat+][X−—Z-Bas] wherein:
[Cat+] represents one or more cationic species;[X−—Z-Bas] represents one or more anionic species wherein:X− represents an anionic moiety;Z is a covalent bond joining X− and Bas, or a divalent linking group; andBas is a basic moiety, in an amount of from 1 to 5,000 ppm by weight, based on the total weight of the corrosive fluid. |
