Dichloro(difluoro)methane

Dichloro(difluoro)methane is a chlorofluorocarbon compound with the chemical formula CCl2F2 and molecular weight of 120.91 g/mol. Also known as CFC-12 or Freon-12, it belongs to the family of halogenated hydrocarbons where hydrogen atoms in methane are replaced by chlorine and fluorine atoms. This synthetic chemical compound has been widely used in industrial applications due to its unique properties as a refrigerant and propellant.

Dichloro(difluoro)methane is a colorless gas at room temperature with a faint, sweet odor. It has excellent chemical stability and low reactivity under normal conditions. The compound is non-flammable and has low solubility in water but is soluble in organic solvents. It exhibits low toxicity at normal exposure levels and has a boiling point of approximately -29.8°C, making it suitable for refrigeration applications.

Dichloro(difluoro)methane is primarily used as a refrigerant in air conditioning and refrigeration systems, particularly in older equipment. It serves as a propellant in aerosol products and as a blowing agent for foam production. Industrial applications include use as a solvent for cleaning and degreasing operations. However, due to environmental concerns regarding ozone depletion, its use has been significantly restricted and phased out in many applications under international environmental protocols.

Dichloro(difluoro)methane should be handled in well-ventilated areas to prevent accumulation of vapors. Wear appropriate personal protective equipment including safety goggles and chemical-resistant gloves. Avoid contact with hot surfaces or flames, and ensure adequate ventilation to prevent oxygen displacement in confined spaces. Use proper gas handling equipment and pressure regulators when working with pressurized containers. Regular monitoring of atmospheric concentrations is recommended in enclosed work areas.

Dichloro(difluoro)methane should be stored in properly labeled, pressure-rated containers in cool, dry, well-ventilated areas away from heat sources and direct sunlight. Store cylinders in upright position and secure them to prevent falling. Avoid storage near incompatible materials such as strong bases, reactive metals, and oxidizing agents. Maintain storage temperatures below 40°C and ensure adequate ventilation to prevent vapor accumulation. Regular inspection of storage containers is essential.

Dichloro(difluoro)methane exposure requires immediate action depending on the route of contact. For skin contact, remove contaminated clothing and wash affected area with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention if breathing difficulties occur. For suspected ingestion, do not induce vomiting and seek immediate medical attention.

Dichloro(difluoro)methane must be disposed of in accordance with local environmental regulations and international protocols due to its ozone-depleting potential. Contact licensed hazardous waste disposal companies for proper collection and treatment. Do not release into the atmosphere or dispose of in regular waste streams. Recovery and recycling through specialized facilities is preferred when possible. Ensure compliance with the Montreal Protocol restrictions and local waste management regulations for halogenated compounds.

Dichloro(difluoro)methane is classified as ADR Class 2 dangerous goods for transportation purposes. It must be transported in approved pressure containers with proper labeling and documentation. Vehicles must carry appropriate emergency equipment and drivers require hazardous materials training certification. Ensure containers are secured properly during transport and avoid exposure to excessive heat or mechanical damage. Comply with routing restrictions and emergency response procedures specified in transportation regulations.

Dichloro(difluoro)methane is subject to strict international and European regulations due to its ozone-depleting properties. It is regulated under the Montreal Protocol and EU Ozone Regulation, with production and use heavily restricted or banned in most applications. Under REACH regulation, it requires registration for industrial use. The compound is not classified as SVHC, but its environmental impact makes it subject to phase-out schedules and licensing requirements for remaining permitted uses.

Dichloro(difluoro)methane can be sourced through specialized chemical distributors like OYSI, which serves the European market with industrial chemicals. Due to regulatory restrictions, availability is limited to specific licensed applications such as essential industrial processes or laboratory use. Purchasers must demonstrate compliance with applicable regulations and possess proper handling licenses. Contact OYSI for availability, regulatory compliance support, and technical specifications for your specific application requirements.
