Tris(2-ethylhexyl) Phosphate(TOP)

Product Name Tris(2-ethylhexyl) Phosphate(TOP)
Cas No. 78-42-2
Molecular formula


Molecular weight 434.64
Quality Index

●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.
