Description

n-[(5,5-Dimethyl-1,3,2-Dioxaphosphorinane 2-Oxide)-2-Yl]-N'-[(Z)-9-Octadecenyl]-1,3-Propanediamine is a specialized organophosphorus compound featuring a unique cyclic phosphonate ester group linked to a long-chain oleylamine derivative. This molecular architecture provides exceptional surface-active and chelating properties, making it a high-performance additive for demanding industrial formulations. It is primarily sought by manufacturers in the lubricant, metalworking fluid, and polymer stabilization industries who require advanced multifunctional performance from a single molecule.

Application

• As a high-performance extreme pressure (EP) and anti-wear additive in synthetic and semi-synthetic metalworking fluids and industrial lubricants.
• As a multifunctional stabilizer and chelating agent in polymer formulations, particularly for PVC and other halogenated polymers.
• As a corrosion inhibitor and metal passivator in functional fluid packages for automotive and aerospace applications.
• As a specialized surfactant and emulsifier for formulating high-stability oil-in-water emulsions.
• As a key intermediate in the synthesis of more complex phosphonate-based specialty chemicals.
• In textile auxiliaries as a softening and lubricating agent for synthetic fibers.
