Product Details

Products Description of PHOSPHORIC ACID CAS#78-42-2

PHOSPHORIC ACID is widely used as a flame retardant, plasticizer, and extraction agent in the production of chemical companies. Its most important use is the production of hydrogen peroxide. Chemicalbook trioctyl phosphate, as a solvent for hydroanthraquinone, has the following conditions: high solubility of hydroanthrone, high distribution coefficient of hydrogen peroxide between water and solvent, high boiling point, and high flash point.
