Tris(3,5-dimethylphenyl) phosphate(CAS: 25155-23-1)

Tris(3,5-dimethylphenyl) phosphate (CAS: 25155-23-1) is a colorless, viscous liquid with a molecular weight of approximately 324.4 g/mol. It has a low volatility and is slightly soluble in water but soluble in common organic solvents. This compound is relatively stable under normal conditions but can react with strong oxidizers to release toxic gases. It is used as a flame retardant and plasticizer.

Tris(3,5-dimethylphenyl) phosphate is synthesized via a multistep process involving the reaction of 3,5-dimethylphenol with phosphorus oxychloride in the presence of a catalyst such as aluminum chloride. The reaction is exothermic, and the product is purified by distillation. The process typically yields a high purity product with good selectivity and yield.

Tris(3,5-dimethylphenyl) phosphate (CAS: 25155-23-1) is widely used in the polymer industry as a flame retardant and plasticizer. It is also used in the manufacturing of electronic materials, adhesives, and sealants. Due to its excellent flame-retardant properties, it is a key component in the production of plasticized polyurethanes and polyesters.

Tris(3,5-dimethylphenyl) phosphate should be handled with appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from strong oxidizers. In case of spill, use proper containment and clean up with care. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
