Trioctyl Phosphate 

  

Chemical formula and molecular weight

Chemical formulaC24H51O4P

Molecular weight434.64

CAS No.78-42-2

 Properties and uses

Colourless,transparent oily liquid,b.p.2164mmHg,viscosity 14 c.p.20),refractive index 1.443420.

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.
