Description

Octylphenyl Dihydrogen Phosphate is an organophosphorus compound widely used as an intermediate and functional additive. Its value lies in its ability to act as an effective acid catalyst, metal extractant, and surface-active agent in various high-performance formulations. This product is essential for manufacturers in the chemical synthesis, polymer, and lubricant industries seeking specialized phosphoric acid derivatives.

Application

• Chemical Synthesis Intermediate: A key building block for producing more complex phosphate esters, surfactants, and flame retardants.
• Acid Catalyst: Used in esterification, polymerization, and other organic synthesis reactions where a controlled acidic environment is required.
• Metal Extraction & Separation: Functions as a selective extractant for rare earth metals and other valuable ions in hydrometallurgical processes.
• Lubricant & Fuel Additive: Imparts anti-wear and extreme pressure properties to industrial lubricants and functional fluids.
• Surfactant & Emulsifier Precursor: Serves as a raw material for manufacturing specialized anionic surfactants with unique wetting and dispersing characteristics.
• Flame Retardant Synergist: Used in combination with other compounds to enhance flame-retardant efficacy in plastics and polymers.
