ABSTRACT:
This invention relates to a process of inhibiting corrosion which comprises adding an aqueous soluble form of a normally insoluble corrosion inhibitor to an aqueous system which converts the soluble corrosion inhibitor to an insoluble form which coats the metal with a corrosion inhibiting film.
For example, a water insoluble heterocyclic amine used as a water soluble salt is dissolved in an aqueous system having a pH in excess of about 6 where the heterocyclic amine itself, i.e., in non-salt form, comes out of solution as a stable, fine dispersion which coats the metal with a uniform and tenacious corrosion inhibiting film.
