Description

Diisotridecyl Hydrogen Phosphate is an organophosphorus compound widely used as an intermediate, extractant, and acid catalyst in industrial synthesis. Its value lies in its role as a key building block for producing specialized surfactants, lubricant additives, and metal extraction agents. This product is essential for manufacturers in the chemical, polymer, and lubricant industries seeking to develop high-performance formulations.

Application

• Metal Extraction & Separation: Acts as a selective extractant for rare earth elements and transition metals in hydrometallurgical processes.
• Polymer & Plastic Additives: Serves as an intermediate in the synthesis of phosphite and phosphate-based antioxidants and stabilizers for plastics.
• Lubricant & Fuel Additives: Used to produce anti-wear and extreme pressure (EP) additives for industrial lubricants and functional fluids.
• Surfactant Synthesis: A key precursor for manufacturing specialized anionic and nonionic surfactants with emulsifying and wetting properties.
• Acid Catalyst: Functions as a catalyst or co-catalyst in various organic synthesis and esterification reactions.
• Flame Retardant Intermediate: Employed in the production of organophosphorus flame retardants for polymeric materials.
