Trioctyl Phosphate

Category: Organophosphates

Description: Trioctyl phosphate, also known as tris(2-ethylhexyl) phosphate or TOP, is a triakylphosphate in the organophosphate group. Trioctyl phosphate features low volatility and high thermal stability. It is widely used as a fire-retardant, plasticizer, defoamer, solvent for hydrogen peroxide production, etc.

Applications:


Trioctyl phosphate finds applications as a solvent in the synthesis of hydrogen peroxide by the anthraquinone process, in order to improve quality, increase efficiency, and make the process more environmentally friendly.


Trioctyl phosphate is used as a plasticizer in polymers such as polyvinyl chloride (PVC) and synthetic rubber, giving them higher flexibility and better resistance to low temperatures.


Due to its excellent flame retardancy, trioctyl phosphate is also used for producing flame retardant and self-extinguishing products.


Further, trioctyl phosphate works as a diluent for pigments and resins used in coatings and printing inks.
