Description

Phosphoric Acid, Decyl Octyl Ester is a specialized organophosphorus compound widely utilized as a high-performance intermediate and functional additive. Its molecular structure, combining decyl and octyl chains with a phosphate group, provides excellent solubility in organic media and valuable surface-active properties. This ester is particularly sought after by formulators in the lubricant, plasticizer, and specialty chemical industries for its role in enhancing product performance and stability.

Application

• As an anti-wear and extreme pressure (EP) additive in synthetic lubricants and hydraulic fluids.
• Functioning as a plasticizer and stabilizer in polymer and resin formulations, including PVC and other vinyl polymers.
• Used as a surfactant and emulsifying agent in industrial cleaning products and degreasers.
• Employed as a corrosion inhibitor in metalworking fluids and industrial coatings.
• Serving as a key intermediate in the synthesis of more complex phosphate esters and flame retardants.
• Acting as a dispersant and processing aid in pigment masterbatches and specialty inks.
