Chlorine trifluoride

Compressed liquefied gas almost colorless, odor. In the liquid is yellow-green. In solid white.

It is denser than air and corrosive.

The substance decomposes above 220 °C producing toxic gases (chlorine, fluorine). Reacts violently with water, sand, silicon-containing compounds, glass and asbestos; reacts with all forms of plastics, rubber and resins, except highly fluorinated polymers. On contact with this substance most combustible materials ignite spontaneously. Reacts violently with oxidizing agents, metals and metal oxides. Explodes on contact with organic materials. Emits highly toxic fumes on contact with acids.
