Vote count: 0. One such compound is dioxygen difluoride, generally referred to as FOOF. Not only did Streng prepare multiple batches of dioxygen difluoride and keep it around, he was apparently charged with finding out what it did to things. Dioxygen difluoride is a compound of fluorine and oxygen with the molecular formula O 2 F 2.It can exist as an orange-colored solid which melts into a red liquid at −163 °C (110 K). For a long time, it looked as though FOOF would go on to have no practical use beyond endangering the lives of scientists. : The latest addition to the long list of chemicals that I never hope to encounter takes us back to the wonderful world of fluorine chemistry.

[6][7], O2F2 precipitates as a brown solid upon the UV irradiation of a mixture of liquid O2 and F2 at -196 °C. Let’s put it this way: compared to FOOF, chlorine trifluoride isn’t reactive at all…and CTF is the stuff most famous for being able to set asbestos on fire. The hexafluorides can then be fed back into the nuclear fuel cycle. This site uses cookies from Google and other third parties to deliver its services, to personalise adverts and to analyse traffic.

Fig. Most famous is the work of Alex G Streng, one part of a dynamic husband-and-wife duo, who dedicated the bulk of their careers to the adventurous pursuit of fluoride compounds. Dioxygen difluoride reacts with xenon at about 118 o C to give XeF 2.; Xe + O 2 F 2 → XeF 2 + O 2. [8] It also only appears to be stable below -160 °C. You get the picture. First synthesised in Germany in the 1930s by inorganic chemists Otto Ruff and Walter Menzel, FOOF belongs to the oxygen fluorides, a highly dangerous class of oxidants. Used to kill bacteria, power lasers and tracers as an antiseptic. The compound has no practical applications, but has been of theoretical interest. 27 0 obj<>stream How long will the footprints on the moon last?

Perfluoroperoxide. Used to oxidize and fluorinate the hetero element in an organometallic compound, but does not attack the alkyl or aryl groups; Used as a very convenient for the detection and determination of very small amounts of iodine and iodide based on the oxidation of iodine to periodate. A chemical so explosive, no one should ever go near it – except to recover nuclear fuel. Difluorine monoxide, or oxygen difluoride, has OF2 for its chemical formula.

Submit Rating . One laboratory used it to synthesize plutonium hexafluorideat unprecedentedly low temperatures, which was significant because previous methods for preparation needed temperatures so high that the plutonium hexafluoride created would rapidly decompose. 0000064760 00000 n 0000005582 00000 n Dioxygen Difluoride O2F2 Molar Mass, Molecular Weight. There has been speculation about the existence of other oxygen fluorides (03F2, 03F, OSF2 and 06F2) but these have not been well-characterized. The other product, oxygen difluoride, is almost as strong an oxidizer as dioxygen difluoride, which is only stronger because it's oxygen difluoride plus more oxygen. 0000006432 00000 n Dioxygen difluoride can be obtained by subjecting a 1:1 mixture of gaseous fluorine and oxygen at low pressure (7–17 mmHg is optimal) to an electric discharge of 25–30 mA at 2.1–2.4 kV.This is basically the reaction used for the first synthesis by Otto Ruff in 1933.
