C2F4
C2F4, also known as 1,2-difluoroethene, is a chemical compound with the molecular formula CH2=CF2. It is a colorless gas with a sweet, ether-like odor. C2F4 is a member of the family of haloalkenes, which are unsaturated hydrocarbons containing one or more halogen atoms. It is a versatile intermediate in the chemical industry, used primarily in the production of polytetrafluoroethylene (PTFE), commonly known as Teflon. This process involves the polymerization of C2F4 to form long chains of PTFE, which is then used in various applications due to its excellent chemical resistance and low friction properties. C2F4 is also used in the production of other fluoropolymers and as a refrigerant in some specialized applications. The compound is typically handled as a liquefied gas under pressure and is known for its high reactivity and potential hazards, including being a strong irritant to the skin, eyes, and respiratory system. Proper safety measures, including the use of personal protective equipment and ventilation, are essential when working with C2F4.
