Useful:

Chemical Classes:Toxic Gases & Vapors -> Oxidizers
Canonical SMILES:O(F)F
Inhalation Risk:A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
Effects of Short Term Exposure:Lachrymation. The substance is irritating to the respiratory tract. Inhalation of this gas may cause lung oedema. Exposure slightly above the OEL could cause death.
Physical properties Colorless gas with a characteristic odor; unstable in the presence of moisture, otherwise stable up to 250°C; gas density 2.21g/L at 25°C; liquefies to a yellowish-brown liquid at -144.8°C; density of the liquid 1.90g/ml at -223.8°C; solidifies at -223.8°C; slightly soluble in water, decomposing very slowly; solubility 68ml gas per liter of water at 0°C; slightly soluble in acids and alkali.
Uses Commercial applications of oxygen difluoride are limited. It is used in organic synthesis to prepare fluoropropylenes and acylfluorides. It is used as an oxidizing and fluorinating agent in many preparative reactions and as a monomer in diolefin copolymerization. Oxidant in missile propellant systems
