CAS No:78-42-2
Molecular formula:C24H51O4P
Molecular weight:434.64 (International Atomic Weight Table,1987)
Molecular structure:

Properties:transparent oily liquid,b.p.216℃(4mmHg),viscosity 14 c.p.(20℃),refractive index 1.4434(20℃).
Uses:
(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.
Package:180kg /iron drum net each,1000L/IBC drum.
Storage and transportation:
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.
