Tris (chloroisopropyl) phosphate (TCPP)

TCC’s Tris (chloroisopropyl) phosphate (TCPP) is a colorless or light yellow transparent liquid. Its molecular formula is C9H18Cl3O4P. The chemical is used as a low-cost flame inhibitor in the production of bar-shaped and lump-shaped foam. Other applications include use as raw material for the manufacture of polyester foam plastic, binder and other resins.

TCCP is harmful if swallowed and is irritating to the respiratory system. The liquid chemical does not dissolve in water, but it can dissolve in organic solvents such as ethyl alcohol, acetone and others. TCPPhas good heat conductivity and is a hydrolysis stabilizer with good retarding ability for containing phosphor and chlorine. TCPP is normally used at 10~15 phr depending on applications.

Applications

TCC’s Tris(1-chloro-2-propyl) phosphate (TCPP) is primarily used as a flame retardant in rigid and flexible polyurethane foam. Specifically, it is used as a flame inhibitor in the production of bar-shaped or lump-shaped foam. It is a low-cost flammable inhibitor and a good stabilizer. Other applications include use as raw material for the manufacture of polyester foam plastic, binders and other resins.

Description

TCC’s Tris(1-chloro-2-propyl) phosphate (TCPP) is a clear colorless liquid that is stable at ambient temperature and is not volatile. Its molecular formula is C9H18Cl3O4P. It is manufactured to a purity of 75 ± 10%. Major impurities are bis(1-chloro-2-propyl)-2-chloropropyl phosphate (20-30%) and bis(2-chloropropyl)-1-chloro-2-propyl phosphate (3-5%).

TCPP is harmful if swallowed, and is irritating to the respiratory system. If ingested, the targeted organs are the liver and bladder.

TCPP can be manufactured by either a batch or continuous process. TCPP is the reaction of phosphorous oxytrichloride with propylene oxide in the presence of a catalyst. The reaction is carried out in a closed reactor. The crude product is washed and dehydrated in a closed vessel to remove acidic impurities and residual catalyst. All transfers are done using closed lines. The product is then filtered, transferred, and packaged using sealed pumps through closed lines. Storage is in closed vessels under nitrogen to exclude moisture and oxygen. TCPP is used as a flame retardant in rigid and flexible polyurethane foam. Its known use is industrial.
