Dichlorofluoroethane, chemically known as 1,1-dichloro-1-fluoroethane and designated by the CAS number 1717-00-6, is a compound with distinct physical and chemical characteristics that dictate its industrial applications and handling requirements. Understanding these properties is crucial for anyone involved in its manufacture, distribution, or use.

Physically, Dichlorofluoroethane is typically described as a colorless liquid with a mild, somewhat ethereal or sweetish odor. Its volatility is a key characteristic, with a boiling point of approximately 32°C, meaning it readily transitions into a gaseous state at room temperature. This property makes it suitable for applications where evaporation is desired, such as in cleaning processes or as a blowing agent. Its density is greater than water, and it is sparingly soluble in water but soluble in many organic solvents, a trait that contributes to its effectiveness as a cleaning agent.

Chemically, Dichlorofluoroethane is a hydrochlorofluorocarbon (HCFC). While it is considered more stable and less damaging to the ozone layer than older chlorofluorocarbons (CFCs), it still possesses ozone-depleting potential and contributes to global warming. Its reactivity profile indicates stability at room temperature but potential reactions with strong oxidizing or reducing agents. Awareness of its flammability is also important; while often classified as non-flammable, under certain conditions or when contained in an emptied drum that is then cut, it has shown potential for ignition.

The health and safety considerations associated with Dichlorofluoroethane are vital. Exposure can cause irritation to the eyes, skin, and respiratory tract. Inhalation of high concentrations may lead to central nervous system effects such as dizziness or anesthetic effects. Therefore, proper handling procedures are essential. This includes working in well-ventilated areas, using appropriate personal protective equipment (PPE) such as gloves, eye protection, and respirators when necessary, and adhering strictly to safety data sheet (SDS) recommendations.

Manufacturers and suppliers of Dichlorofluoroethane, especially those based in China, emphasize product purity (≥99.5%) and adherence to international quality standards. When sourcing this chemical, users should always request and review the SDS to fully understand the hazards, safe handling, storage, emergency procedures, and disposal guidelines. This ensures that operations involving Dichlorofluoroethane are conducted with the highest regard for safety and environmental responsibility.
