摘要： Disclosed herein are corrosion control compositions comprising one or more multiple charged cationic compounds 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 compositions are found to be effective corrosion inhibitors for water systems.

摘要： Methods of employing corrosion inhibitors with oxidizing and/or non-oxidizing biocides, such as peroxycarboxylic acids, to provide corrosion protected compositions are disclosed. Various corrosion inhibitors further provide biocidal efficacy in addition to the corrosion protection providing further benefits for application of use. Methods of employing corrosion protected biocide compositions, such as peroxycarboxylic acid compositions, for corrosion protection are particularly well suited for treating fluids intended to flow through pipes, namely in the energy industry, water and paper industries, etc. Methods providing suitable corrosion protection in comparison to untreated systems and corrosion protected systems using conventional corrosion inhibitors, such as quaternary amines and imidazolines commonly used in the industry, are disclosed.

摘要： Disclosed herein are the methods of using di-cationic or di-anionic compounds, which are derived from primary amine through an aza-Michael addition with an activated olefin, in a corrosion control composition to mitigate corrosion of a surface in a water system. The disclosed methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for mitigating corrosion for a metal surface in water systems.

摘要： A polyhydroxypolycarboxylic acid and a water soluble phosphino polycarboxylate may be added to an aqueous system, such as a cooling water system, in order to inhibit corrosion as well as the deposition of corrosion within the system. The water soluble phosphino polycarboxylate may be derived from a phosphinyl unsaturated monomer and an ethylenically unsaturated carboxylic acid monomer. The aqueous system may be a cooling water system such as a cooling tower, a closed cooling water system, an air-conditioning water systems, a wastewater treatment system as well as a deionized water production system.
