Chloro(trifluoro)methane

Chloro(trifluoro)methane is a halogenated hydrocarbon with the chemical formula CClF3 and CAS number 75-72-9. This compound belongs to the chlorofluorocarbon (CFC) family and has a molecular weight of 104.46 g/mol. It is a synthetic chemical compound containing one chlorine atom and three fluorine atoms bonded to a central carbon atom, making it a fully halogenated methane derivative.

Chloro(trifluoro)methane is a colorless gas at room temperature and atmospheric pressure with characteristic properties typical of CFCs. It exhibits low boiling point, chemical stability, and low reactivity under normal conditions. The compound is relatively inert due to the strong carbon-fluorine bonds and shows limited solubility in water while being more soluble in organic solvents.

Chloro(trifluoro)methane is primarily used as a refrigerant in specialized cooling applications and as a propellant in aerosol products. It serves in industrial processes requiring inert atmospheres and as an intermediate in chemical synthesis. Due to environmental regulations concerning CFCs, its applications have become more restricted and specialized, focusing on essential uses where alternatives are not readily available.

Chloro(trifluoro)methane should be handled in well-ventilated areas or under fume extraction systems to prevent inhalation. Personnel should wear appropriate personal protective equipment including safety goggles and protective gloves. Avoid exposure to high temperatures or ignition sources, and ensure proper training on gas handling procedures. Work in areas equipped with gas detection systems when handling significant quantities.

Chloro(trifluoro)methane must be stored in appropriate pressure vessels designed for compressed gases, in cool, dry, and well-ventilated areas away from heat sources and direct sunlight. Storage areas should be separated from incompatible materials and equipped with proper ventilation systems. Regular inspection of storage containers and pressure relief systems is essential for safe storage.

Chloro(trifluoro)methane exposure requires immediate removal from the exposure area to fresh air in case of inhalation. For skin or eye contact, rinse thoroughly with clean water for at least 15 minutes. Remove contaminated clothing and seek medical attention if symptoms persist. In case of significant exposure or breathing difficulties, obtain immediate medical care and provide the safety data sheet to medical personnel.

Chloro(trifluoro)methane must be disposed of through licensed waste management companies specialized in handling CFCs due to environmental regulations. The compound should never be released directly into the atmosphere due to its ozone depletion potential. Recovery and recycling programs are preferred when available, and destruction must be performed using approved high-temperature incineration methods at authorized facilities.

Chloro(trifluoro)methane is classified under ADR Class 2 (gases) for transportation purposes. It must be transported in appropriate pressure vessels meeting transportation standards and properly labeled according to dangerous goods regulations. Vehicles must be equipped with proper ventilation and emergency equipment, and drivers require hazardous materials transportation certification for commercial transport.

Chloro(trifluoro)methane is subject to strict environmental regulations including the Montreal Protocol due to its ozone depletion potential. Under EU regulations, it falls under REACH registration requirements and CLP classification standards. The compound is heavily regulated under ozone-depleting substance legislation, with restrictions on production, import, and use in many applications across European markets.

Chloro(trifluoro)methane can be purchased through OYSI, a specialized European distributor of technical chemicals with expertise in regulated substances. OYSI provides professional support for compliance with environmental regulations and proper handling requirements. Due to regulatory restrictions on CFCs, procurement requires verification of authorized use and compliance with applicable environmental legislation.
