Carbon Tetrachloride

Carbon Tetrachloride

Carbon tetrachloride, also known as tetrachloromethane, is the raw material for the chlorofluorocarbons CFC-11 and CFC-12. These two ozone-depleting agents were completely phased out worldwide by the end of 1999. Demand for carbon tetrachloride is still growing as an intermediate for the production of pentafluoropropane (HFC-245fa) and pentafluorobutane (HFC-365mfc), fluorocarbons now used as foam blowing agents mainly in the United States. Carbon tetrachloride is also a raw material for tetrachloropropene, which is itself a raw material for the new generation of hydrofluoroolefins (HFO) refrigerants, which are a climate-friendly alternative to HFCs and HCFCs.
