  • Patent number: 11359291
    Abstract: Disclosed here are the methods of using one or more multiple charged cationic compounds in a corrosion control composition to reduce corrosion of metal surfaces in a water system. The multiple charged cationic compounds are derived from polyamines through a ring-opening reaction with an epoxide or two reactions: an aza-Michael addition with an activated olefin having a cation group and a ring-opening reaction with an epoxide. The disclosed methods or compositions are found to be effective than those methods or compositions including commonly used corrosion inhibitors for water systems.
