Tris(2-Chloroisopropyl) Phosphate: A Comprehensive Guide to its Properties, Applications, and Safety
Tris(2-chloroisopropyl) phosphate (TCPP) is a colorless to light yellow liquid that belongs to the family of organophosphorus compounds. It is mainly used as a flame retardant plasticizer in various polymers, including polyurethane foams, PVC, and cellulose acetate. TCPP is known for its excellent flame retardant properties, low volatility, and thermal stability. In this article, we will provide a comprehensive guide to TCPP, including its properties, applications, and safety considerations.
Properties of Tris(2-Chloroisopropyl) Phosphate
Chemically, TCPP is classified as a trialkyl phosphate ester, with the chemical formula C9H18Cl3O4P. It has a molecular weight of 327.6 g/mol and a boiling point of 270-275 °C. TCPP is soluble in most organic solvents, including acetone, toluene, and chloroform, but insoluble in water.
One of the key properties of TCPP is its excellent flame retardant properties. It works by releasing phosphoric acid during combustion, which forms a protective layer of char that prevents further burning. TCPP is also known for its low volatility, which makes it suitable for use in high-temperature applications. Additionally, TCPP has good plasticizing properties, which improve the flexibility and durability of the polymers it is used in.
Applications of Tris(2-Chloroisopropyl) Phosphate
TCPP is mainly used as a flame retardant plasticizer in various polymers, including polyurethane foams, PVC, and cellulose acetate. In polyurethane foams, TCPP is used as a secondary flame retardant to improve the fire resistance of the foam. It is also used as a plasticizer to improve the flexibility of the foam.
In PVC, TCPP is used as a primary flame retardant, providing excellent fire resistance to the material. It is also used as a plasticizer to improve the processing and mechanical properties of the PVC. In cellulose acetate, TCPP is used as a flame retardant plasticizer to improve the fire resistance and mechanical properties of the material.
Apart from its use in polymers, TCPP is also used as a flame retardant in other applications, including textiles, coatings, and adhesives. It is also used as a lubricant and antiwear agent in metalworking fluids and as a solvent in the synthesis of other organophosphorus compounds.
Safety Considerations of Tris(2-Chloroisopropyl) Phosphate
TCPP is classified as a hazardous substance under various regulations, including REACH, CLP, and OSHA. It is toxic by ingestion and inhalation, and may cause irritation to the skin and eyes. Long-term exposure to TCPP may cause damage to the liver, kidneys, and central nervous system.
To minimize the risks associated with TCPP, it is important to handle it with care and follow the recommended safety precautions. This includes wearing protective clothing and equipment, such as gloves, goggles, and a respirator, when handling TCPP. It is also important to store TCPP in a cool, dry, and well-ventilated area away from sources of ignition.
Conclusion
Tris(2-chloroisopropyl) phosphate is a versatile organophosphorus compound that is widely used as a flame retardant plasticizer in various polymers. It is known for its excellent flame retardant properties, low volatility, and thermal stability. However, it is important to handle TCPP with care and follow the recommended safety precautions to minimize the risks associated with it.
