Abstract
Disclosed are sulfide-based compounds which are a product of a Michael addition reaction between a sulfur-containing donor group and an unsaturated hydrocarbon moiety. The sulfide-based compounds may be used in compositions and methods for inhibiting corrosion.
Claims18
A corrosion inhibition composition comprising at least one cationic or anionic sulfide-based compound comprising an OH group and a quaternary ammonium group or a sulfonate group, the at least one sulfide-based compound formed by a Michael addition reaction between a sulfa-Michael donor and a Michael acceptor comprising a carbon-carbon double bond, wherein the sulfa-Michael donor comprises a mercaptoalcohol, and wherein the Michael acceptor comprises an anionic sulfonate group or a cationic quaternary ammonium group.
