High-Performance DEA Chemical – Diethanolamine for Gas Treating & Surfactant Manufacturing
Diethanolamine Product Introduction
Diethanolamine (DEA) is a key industrial amine widely applied in gas processing, personal care surfactants, and corrosion inhibition systems. Its balanced alkalinity and high water compatibility make it ideal for multi-functional formulations.
Diethanolamine Key Features
CO₂ & H₂S absorption grade | stable cycle performance
High activity for fatty acid reaction in ethanolamide syntheses
Low metal residue | meets industrial & semi-cosmetic standards
Excellent pH buffering & foam control properties
Ideal for detergent, refinery, agrochemical & auxiliary industries
Diethanolamine Applications
Refinery & syngas desulfurization system
Mild foam surfactants (e.g. DEA lauramide)
Metal machining and protective fluid systems
Concrete additives & polymer processing
Rust inhibitors & textile finishing
