(trifluoromethane), CHF3, a colorless gas, with a boiling point of –82.5°C. Unlike chloroform, fluoroform is an inert compound; for example, it is resistant to the action of alkalies. It is prepared from chloroform by an exchange reaction with SbF3 or HF or from chlorotrifluoromethane (Freon-13) and H2, as well as by other methods. It is used as a refrigerant.
