Obtained by treating hexachloroethane with anhydrous fluoride in the presence of small amounts of antimony chloride under high pressure.、The most important commercial method for manufacturing CFCs and HCFCs is the successive replacement of chlorine by fluorine using hydrogen fluoride. The traditional、liquid-phase process uses antimony pentafluoride or a mixture of antimony trifluoride and chlorine as catalysts. Continuous vapor-phase processes that employ gaseous hydrogen fluoride in the presence of heterogenous chromium、iron、or fluorinated alumina catalysts also are widely used. Carbon tetrachloride、chloroform、and hexachloroethane (or tetrachloroethylene plus chlorine) are commonly used starting materials for one- and two-carbon chlorofluorocarbons. The extent of chlorine exchange can be controlled by varying the hydrogen fluoride concentration、the contact time、or the reaction temperature.、CFCs and HCFCs、Impurities: Chlorofluoroalkanes (and also the alternative HCFCs and HFCs) produced on an industrial scale are subject to stringent standards. Impurities must not exceed the following limits (vol %): acids、moisture、<0.001、higher-boiling fractions、<0.05、and other gases、2.、Chlorofluoroalkanes、Formulations、Preparations: USEPA、OPP Pesticide Code 326200、Trade Names: Propellant 114 and Cryofluorane.、Former trade names、Grades: Technical 95%.、Consumption Patterns: For low molecular weight fluorinated hydrocarbons) 43% as aerosol propellant、32% as refrigerant、10% for synthesis of resins、5% as solvent and degreaser、4% as foam-blowing agent、6% for misc uses including exports (1969)、CFC-114 ... is mainly used with centrifugal compressors、for refrigerant applications、(1984)、Refrigeration、air conditioning、43%、foam blowing agents、20%、polymer precursors、13%、solvent cleaning、12% aerosol propellants、2%、medical equipment sterilization、3%、other、7%.
