Tri-iso-octyl Phosphate(TOP)

(1) 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.(2) 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.
