CClF3

CClF3, also known as chlorotrifluoromethane or Freon 13, is a halocarbon with the chemical formula CClF3. It is a colorless gas at standard temperature and pressure. This compound is a derivative of methane where one hydrogen atom is replaced by chlorine and the other three hydrogen atoms are replaced by fluorine. CClF3 is a greenhouse gas and has a high global warming potential.

Historically, chlorotrifluoromethane was used in some specialized refrigeration applications and as a propellant in aerosols. However, due to its environmental impact, its production and use have been significantly restricted under international agreements like the Montreal Protocol, which aims to phase out ozone-depleting substances and reduce greenhouse gas emissions.

The compound is chemically stable and non-flammable. Its synthesis typically involves the reaction of carbon tetrachloride with hydrogen fluoride in the presence of a catalyst. While its direct applications are now limited, understanding its properties and environmental behavior remains important for monitoring atmospheric composition and developing alternative substances.
