Trioctyl Phosphate (TOP) CAS No. 78-42-2

Product Description

Chemical formula and molecular weight
Chemical formula: C24H51O4P
Molecular weight: 434.64
CAS No.: 78-42-2

Properties and uses
Colourless, transparent oily liquid, b. P. 216 oC(4mmHg), viscosity 14 c. P. (20 oC), refractive index 1.4434(20 oC).
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.

Package and storage, safety
Packed in 200 liter galvanized iron drum, net weight 180 kg/drum.
Stored at dry, shady, ventilated place. Prevented from collision and sunrays, rain-attack during handling and shipping.
Met the high hot and clear fire or contact the oxidizing agent, caused the burning danger.
