Tris(2-chloroethyl) phosphate

Tris(2-chloroethyl) phosphate is an organophosphorus compound with the molecular formula C6H12Cl3O4P and CAS number 115-96-8. This chemical substance has a molecular weight of 285.5 g/mol and belongs to the family of chlorinated phosphate esters. It is classified as a hazardous substance with carcinogenic and reproductive toxicity properties, requiring careful handling and compliance with safety regulations in industrial applications.

Tris(2-chloroethyl) phosphate is typically a colorless to pale yellow liquid at room temperature with low volatility. The compound has limited solubility in water but is soluble in organic solvents such as alcohols and aromatic hydrocarbons. It exhibits good thermal stability under normal conditions and has flame-retardant properties due to its phosphorus and chlorine content, making it useful in various industrial formulations.

Tris(2-chloroethyl) phosphate is primarily used as a flame retardant additive in plastics, textiles, and foam materials. It serves as a plasticizer in various polymer applications and is utilized in the production of fire-resistant coatings and adhesives. The compound is also employed in specialized industrial processes where flame retardancy and plasticizing properties are required, particularly in automotive and construction materials.

Tris(2-chloroethyl) phosphate must be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to minimize inhalation exposure. Given its carcinogenic and reproductive toxicity classification (Carc. 2; Repr. 1B), strict adherence to occupational exposure limits and safety protocols is essential to prevent skin contact and inhalation.

Tris(2-chloroethyl) phosphate should be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from heat sources and direct sunlight. Storage areas must be equipped with appropriate containment systems to prevent environmental release. The substance should be kept away from strong oxidizing agents and incompatible materials, with clear labeling indicating its hazardous properties and classification.

In case of skin contact with tris(2-chloroethyl) phosphate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, rinse immediately with clean water for at least 15 minutes and seek medical attention. In case of inhalation, move the person to fresh air immediately. Given its toxic properties, medical consultation should be sought in all exposure cases.

Tris(2-chloroethyl) phosphate must be disposed of as hazardous waste through licensed waste management facilities in accordance with local and European regulations. The substance cannot be discharged into sewers or the environment due to its toxic and persistent properties. Waste containers should be properly labeled and handled by certified waste disposal companies specializing in hazardous chemical waste treatment and destruction.

Tris(2-chloroethyl) phosphate is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transportation purposes. It must be packaged in UN-approved containers with appropriate hazard labels and documentation. Transport vehicles must comply with ADR regulations for Class 9 substances, including proper segregation, emergency equipment, and driver certification requirements for hazardous materials transportation across European borders.

Tris(2-chloroethyl) phosphate is subject to comprehensive European regulations including REACH registration requirements and CLP classification as Carc. 2; Repr. 1B; Acute Tox. 4; Aquatic Chronic 2. The substance requires safety data sheets, exposure scenario documentation, and compliance with occupational exposure limits. Users must implement risk management measures and report downstream use in accordance with REACH obligations and national chemical safety regulations.
