	Oxygen difluoride - Wikipedia, the free encyclopedia
		Oxygen difluoride is the chemical compound with the formula OF It is a powerful oxidant and fluorinating agent.
		The oxygen atom has an oxidation number of +2, unlike almost all other oxygen compounds, where it is −2.
		Oxygen difluoride was first reported in 1929; it was obtained by the electrolysis of molten potassium fluoride and hydrofluoric acid containing small quantities of water.

	Toxicologic Review of Selected Chemicals (Site not responding. Last check: 2007-10-12)
		The revision of the TLV for oxygen difluoride from an 8-hour TWA to a ceiling value reflects the general position of the ACGIH that ceiling TLVs are more appropriate for chemicals that cause acute but not chronic health effects.
		Oxygen difluoride is an unstable, colorless gas with a foul odor.
		Therefore, to reduce the significant risk of acute lung damage associated with brief excursion exposures to oxygen difluoride, OSHA is establishing a ceiling limit of 0.05 ppm for this substance.

	Dioxygen difluoride - Wikipedia, the free encyclopedia
		It is unique amongst oxygen compounds in that oxygen has an oxidation state of +1.
		In all its other compounds (other than peroxides and superoxides), oxygen has an oxidation state of −2, except in oxygen difluoride, OF, where it is +2.
		Dioxygen difluoride can be obtained by subjecting a 1:1 mixture of gaseous fluorine and oxygen at low pressure (7-17 mmgHg is optimal) to an electric discharge of 25-30 mA at 2.1-2.4 kV.

		Human data: Oxygen difluoride is a strong irritant to the entire respiratory tract and causes pulmonary edema and hemorrhage when inhaled for a few hours at 0.5 ppm [Deichmann and Gerarde 1969].
		Basis for revised IDLH: Based on acute inhalation toxicity data in humans [Deichmann and Gerarde 1969], the original IDLH for oxygen difluoride (0.5 ppm) is not being revised at this time.

		With fluorine, the roles of atoms in oxygen compounds are reversed.
		All of the atoms through nitrogen were less electronegative than oxygen, with the result that electron pairs were shifted toward O or donated to O outright.
		and naming the compound oxygen difluoride, rather than difluorine oxide, is a reminder that in this compound fluorine is the more electronegative of the two elements.
