Product Description of Phosphoric Acid CAS# 78-42-2
Phosphoric acid is widely used in the chemical industry as a flame retardant, plasticizer, and extraction agent. Its primary application is in the production of hydrogen peroxide. When used as trioctyl phosphate, it serves as an effective solvent for hydroanthraquinone, offering high hydroanthrone solubility, a high distribution coefficient of hydrogen peroxide between water and solvent, a high boiling point, and a high flash point, ensuring both efficiency and safety in industrial processes.
