Tris(2-ethylhexyl) phosphate CAS 78-42-2 TOP

Trioctyl phosphate is widely used as a flame retardant, plasticizer and extractant in the production of chemical companies, and its most important use lies in the production of hydrogen peroxide. Trioctyl phosphate, as a solvent for hydroanthraquinone, combines the conditions of high solubility of hydroanthraquinone, high partition coefficient of hydrogen peroxide between water and solvent, high boiling point and high ignition point.

1. Performance and use:

Tris(2-ethylhexyl) phosphate, a clear, viscous liquid, is used as a component of vinyl stabilizers, grease additives, and flame-proofing compositions; however, it is used primarily as a plasticizer for vinyl plastic and synthetic rubber compounds.

Tris(2-ethylhexyl) phosphate has been employed as a specialty flameretardant plasticizer for vinyl compositions where low temperature flexibility is critical, eg, in military tarpaulins. It can be included in blends with general purpose plasticizers such as phthalate esters to improve low temperature flexibility.

Tris(2-ethylhexyl) Phosphate is used as a phosphorous flame retardant. 

Tris(2-ethylhexyl) Phosphate is used as a plasticizer in the preparation of a new potentiometric membrane sensor.

Tris(2-ethylhexyl) Phosphate is used as Solvent, antifoaming agent, plasticizer.
