CFC-13like all chlorofluorocarbon compoundscontains atoms of carbon (C), chlorine (Cl), and fluorine (F). 
It can be prepared by reacting carbon tetrachloride with hydrogen fluoride in the presence of a catalytic amount of antimony pentachloride:
CCl + 3HF  CClF + 3HCl
This reaction can also produce trichlorofluoromethane (CClF), dichlorodifluoromethane (CClF) and tetrafluoromethane (CF).
