Dichlorodifluoromethane is an inert synthetic gas that is non-reactive, non-toxic and a gas at room temperature.It belongs to a family of compounds called the chlorofluorocarbons that consist of carbon, chlorine, and fluorine atoms in varying arrangements. It is made by reacting carbon tetrachloride with hydrogen fluoride gas in the presence of a catalyst, usually antimony pentafluoride. It acts as an aerosol spray propellant, and liquid freezant (direct contact freezing agent for food) when compressed in an aerosol can. It was used for air conditioners and refrigerators,as an aerosol propellant for hair sprays, insecticides, paints, adhesives, and cleaners,and as a foaming agent in the manufacture of shipping plastics.It is banned in many countries due to concerns about being a major contributor to ozone depletion.
