The chloro fluoro derivatives of methane and ethane are called freons. Some of the derivatives are: CHF2Cl (monochlorodifluoromethane), CF2Cl2 (dichlorodifluoro-methane), HCF2CHCl2 (1,1-dichloro-2,2-difluoroethane). These derivatives are non-inflammable, colourless, non-toxic, low boiling liquids. These are stable upto 550°C. The most important and useful derivative is CF2Cl2 which is commonly known as freon and freon-12.
Freon or freon-12 (CF2Cl2) is prepared by treating carbon tetrachloride with antimony trifluoride in the presence of antimony pentachloride as a catalyst.
(SbCl5).
3CCl4 + 2SbF3 -----→ 3CCl2F2 + 2SbCl3
Catalyst
Or it can be obtained by reacting carbon tetrachloride with hydrofluoric acid in presence of antimony pentachloride (SbCl5).
CCl4 + 2HF -----→ CCl2F2 + 2HCl
Under ordinary conditions freon is a gas. Its boiling point is -29.8°C. It can easily be liquified. It is chemically inert. It is used in air-conditioning and in domestic refrigerators for cooling purposes (As refrigerant). It causes depletion of ozone layer.

Why does freon come out of a jug liquid if you turn it upside down?
Freon under pressure, much like LP and butane are liquid. At sea level pressure, freon becomes a gas. For freon to work in a refrigeration system, it must be able to transform from liquid to gas to liquid. So, to fill a system, it must be put into that system in liquid form. To do this, the bottle containing freon must be tipped, otherwise only freon the gas would be expelled.
