Tri(2-ethylhexyl)phosphate(TOP)

 Chemical formula and molecular weight
●Chemical formula：C24H51O4P
●Molecular weight：434.64
●
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.
