Ⅰ Chemical formula and molecular weight
●Chemical formula:C24H51O4P
●Molecular weight:434.64
●CAS No.:78-42-2
Ⅱ Properties and uses
●Colourless,transparent oily liquid,b.p.216℃（4mmHg）,viscosity 14 c.p.（20℃),refractive index 1.4434（20℃）.
●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.
