1,1-dichloro-1-fluoroethane

1,1-dichloro-1-fluoroethane is a halogenated hydrocarbon with the molecular formula C2H3Cl2F and CAS number 1717-00-6. This compound belongs to the family of chlorofluorocarbons (CFCs) and has a molecular weight of 116.95 g/mol. It is classified as having chronic aquatic toxicity and ozone-depleting properties, requiring careful handling and regulatory compliance due to its environmental impact.

1,1-dichloro-1-fluoroethane is typically a colorless gas or volatile liquid at room temperature, characteristic of halogenated hydrocarbons. As a halogenated compound, it exhibits low solubility in water but good solubility in organic solvents. The presence of chlorine and fluorine atoms gives it specific density and boiling point characteristics typical of mixed halogenated ethanes, making it useful in specialized industrial applications.

1,1-dichloro-1-fluoroethane is primarily used as an intermediate in chemical synthesis and as a solvent in specialized industrial processes. Due to its halogenated structure, it serves in the production of other fluorinated compounds and can be used in cleaning applications where specific solvency properties are required. However, its use is increasingly restricted due to environmental regulations concerning ozone-depleting substances.

Safe handling of 1,1-dichloro-1-fluoroethane requires appropriate personal protective equipment including chemical-resistant gloves, safety glasses, and respiratory protection when necessary. Work should be conducted in well-ventilated areas or under fume extraction systems to prevent inhalation. The GHS07 pictogram indicates health hazards, so avoid skin and eye contact, and ensure proper training on handling procedures and emergency responses.

1,1-dichloro-1-fluoroethane should be stored in cool, dry, well-ventilated areas away from heat sources and incompatible materials. Use appropriate containers designed for halogenated compounds, ensuring proper sealing to prevent emissions. Storage areas should comply with regulations for ozone-depleting substances and maintain temperature control to prevent excessive vapor pressure buildup. Keep away from strong bases and reactive metals.

In case of skin contact with 1,1-dichloro-1-fluoroethane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water. For eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if symptoms persist. Keep the person warm and at rest, and consult a physician if necessary.

1,1-dichloro-1-fluoroethane disposal must comply with regulations for ozone-depleting substances and hazardous waste management. Contact licensed waste disposal companies specializing in halogenated compounds for proper treatment. Never release to the environment due to its Ozone 1 classification and chronic aquatic toxicity. Disposal methods typically involve high-temperature incineration or specialized recovery processes to prevent environmental release and ozone depletion.

Transportation of 1,1-dichloro-1-fluoroethane should follow dangerous goods regulations, although specific ADR classification details are not provided for this substance. Use appropriate packaging designed for halogenated compounds, ensuring proper labeling with GHS07 pictogram and warning signal word. Carriers should be trained in handling hazardous materials and emergency procedures. Verify specific transport requirements with regulatory authorities before shipment.

1,1-dichloro-1-fluoroethane is subject to various environmental and chemical safety regulations including REACH registration requirements and CLP classification as Aquatic Chronic 3 and Ozone 1. As an ozone-depleting substance, it falls under Montreal Protocol restrictions and EU regulations on ozone-depleting substances. The compound is not currently listed as a SVHC under REACH, but users must comply with classification, labeling, and reporting requirements.
