Downstream Products | Hydrogen peroxide |
Trioctyl phosphate is widely used as a flame retardant, plasticizer, and extractant in the production of chemical enterprises. Its most important use is the production of hydrogen peroxide. As the solvent of hydrogen anthraquinone, trioctyl phosphate has the conditions of high solubility of hydrogen anthrone, high distribution coefficient of hydrogen peroxide between water and solvent, high boiling point and high ignition point.
