The reaction of fluorspar (CaF2) and sulphuric acid yields hydrofluoric acid. CaF2 + H2SO4 → CaSO4 + 2HF. Treatment of chloroform, obtained by reacting methanol and chlorine, with the hydrofluoric acid yields monochlorodifluoromethane, also used as a refrigerant, which is a gas boiling at −°C. CHCl3 + 2HF → CHClF2 + 2HCl.
