ClF<sub>3</sub> - Chlorine Trifluoride

What is Chlorine Trifluoride?

Chlorine trifluoride is an interhalogen compound with the chemical formula ClF3. A severe irritant to the skin, eyes, and mucous membranes is chlorine trifluoride. Lung damage can be caused by exposure to this gas. A 30-minute exposure to 400 ppm was lethal to rats. The mechanism whereby metals resist the attack of elemental fluorine or of chlorine trifluoride is not completely understood. It is a powerful oxidiser and if most combustible material comes in contact with chlorine trifluoride it ignites spontaneously.

Chemical Properties of Chlorine Trifluoride – ClF3

    • Chlorine Trifluoride dissolves in water forms hydrogen fluoride, hydrogen chloride and oxygen. The chemical equation is given below.

ClF3 + 2H2O → 3HF + HCl + O2

    • Chlorine Trifluoride reacts with uranium forms Uranium hexafluoride and a interhalogen compound chlorine fluoride. The chemical equation is given below.

U + 3ClF3 → UF6 + 3ClF

Uses of Chlorine Trifluoride – ClF3

  • Chlorine trifluoride is used as a fluorinating agent. It may be used as an igniter and propellant in rockets.
  • Used in nuclear fuel processing.
  • Used as a fluorinating agent, incendiary, igniter and propellant for rockets, in nuclear reactor fuel processing, pyrolysis inhibitor for fluoro carbon polymers.
