Product name: Tri-iso-octyl Phosphate(TOP)

1  Chemical formula and molecular weightChemical formula:C24H51O4PMolecular weight:434.64CAS No.:78-42-2 2  Properties and usesColourless,transparent oily liquid,b.p200~250°C(5mmHg),viscosity 14 c.p.(20°C),refractive index 1.4434(20°C). It is now chiefly used as a processing solvent,instead of hydroterpineol,for producing hydrogen peroxide by anthraquinone process. It is an ideal solvent in this process,for its low volatility and good extraction distribution coefficient.It is also a cold-resisting and fire-retarding plasticizer applied in ethylenic and cellulosic resins,synthetic rubbers. The cold resisting property is superior to adipate esters.3  Quality standard
