Description

n-(2-Aminoethyl)-N'-[2-(4,5-Dihydro-2-Nonadecyl-1H-Imidazol-1-Yl)Ethyl]Ethylenediamine is a specialized, high-molecular-weight polyamine derivative featuring a long-chain alkyl-substituted imidazoline moiety. This unique structure makes it a highly effective intermediate and functional additive, particularly valued for its surfactant and chelating properties. It is primarily utilized in the formulation of industrial lubricants, corrosion inhibitors, and specialty surfactants for the oil & gas, metalworking, and personal care industries.

Application

• Corrosion Inhibitor Intermediate: A key building block for formulating high-performance, film-forming corrosion inhibitors used in oilfield production, pipelines, and cooling water systems.
• Lubricant Additive: Acts as an extreme pressure (EP) additive and friction modifier in synthetic and semi-synthetic metalworking fluids and industrial lubricants.
• Surfactant Synthesis: Serves as a precursor for cationic and amphoteric surfactants used in fabric softeners, hair conditioners, and other personal care products.
• Chelating Agent: Utilized in water treatment and detergent formulations to sequester metal ions such as calcium and magnesium, preventing scale formation.
• Epoxy Curing Agent: Functions as a hardener for epoxy resin systems, imparting flexibility and improved chemical resistance to the final polymer.
• Asphalt Emulsifier: Employed in the production of cationic asphalt emulsions for road construction and maintenance.
