Tris(2,2,2-trifluoroethyl) phosphate(CAS: 358-63-4)

Tris(2,2,2-trifluoroethyl) phosphate is a colorless or slightly yellowish liquid with a high molecular weight. It has a low boiling point and is poorly soluble in water but miscible with many organic solvents. It is relatively stable under normal conditions but reacts with strong bases. Its molecular weight is approximately 312.13 g/mol. It is used as a flame retardant and plasticizer in various applications.

Tris(2,2,2-trifluoroethyl) phosphate is typically synthesized via the reaction of 2,2,2-trifluoroethanol with phosphorus oxychloride or phosphorus trichloride. The reaction involves the formation of a phosphorus oxyfluoride intermediate, followed by hydrolysis with water or alcohol to produce the desired phosphate ester. The process requires careful control of temperature and reagent ratio to achieve high yield and selectivity.

Tris(2,2,2-trifluoroethyl) phosphate is used in various industries, including pharmaceuticals, polyurethane manufacturing, and flame retardant formulations. It serves as a plasticizer in polymer synthesis and as a flame retardant in electronic and automotive applications. Due to its excellent flame-retardant properties and low toxicity, it is also used in sensor and semiconductor manufacturing processes.

When handling Tris(2,2,2-trifluoroethyl) phosphate, it is crucial to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Ensure that work is conducted in a well-ventilated area or a fume hood to avoid inhalation. Spills should be cleaned up using absorbent materials, and the area should be thoroughly washed down. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
