HZOrganicChem Tri-iso-octyl Phosphate (TOP)

Generic Family: Additive -- Flame Retardant -- Phosphorus Compounds • Supplied by: Hangzhou Nature Organic Chemicals Co., Ltd

I Chemical formula and molecular weight

Chemical formula:C24H51O4P

Molecular weight:434.64

CAS No.:78-42-2

II Properties and uses

Colourless, transparent oily liquid, b.p.216°C(4mmHg), viscosity 14 c.p.(20°C), refractive index 1.4434(20°C).

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.
