Tris(2-chloroethyl) phosphate, also known as tris(2-chloroethyl)phosphoric acid or TCEP, has the chemical formula C6H12Cl3O4P and a molecular weight of 285.49000. It is commonly referred to by its CAS number 115-96-8.
Physical and Chemical Properties: Tris(2-chloroethyl) phosphate is a colorless and transparent liquid with no odor. Its refractive index at 20°C is n20/D 1.472 (literature value). The substance has a flash point of 450 °F, vapor pressure of 0.0045mmHg at 25°C, density of 1.39 g/mL at 25°C (literature value), water solubility of 7 g/L at 20 ºC, melting point of -51 °C, and a boiling point of 192 °C at 10 mm Hg (literature value).
Applications:
This compound serves primarily as a flame retardant and petroleum additive. Due to the presence of both phosphorus and chlorine within its molecular structure, it exhibits significant flame-retardant properties. Besides imparting self-extinguishing characteristics to products, it also improves water resistance, weather resistance, cold resistance, plasticity, and antistatic properties. Tris(2-chloroethyl) phosphate finds wide applications in industries such as rubber, cellulose acetate, nitrocellulose lacquers, ethyl cellulose varnishes, polyvinyl chloride, polyhydroxyethyl acrylate, polyvinyl acetate, and phenolic resins.
