But Streng’s sacrifice of time and safety was not completely wasted. Bear in mind, most of these experiments were performed around -140 °C. Be the first to rate this page. UNII-XWQ158QF24. trailer Asprey cites Streng’s review and praises him for his careful work because without it, Asprey would have been starting from scratch. OXYGEN DIFLUORIDE is an oxidizing agent. 7: Structure of Dioxygen Difluoride. Fig. 0000003261 00000 n 0000012172 00000 n Would that be “dioxygen difluoride”? O 2 F 2 precipitates as a brown solid upon the UV irradiation of a mixture of liquid O 2 and F 2 at -196 °C. Highly toxic by inhalation. Can explode on contact with water.Decomposes to toxic gaseous fluorine if heated to high temperature. 24 35 Not as far as I can see. Average rating 0 / 5. 23 February, 2010. Flames and an explosion. Prolonged exposure of the containers to high heat may result in their violent rupturing and rocketing. 0000051978 00000 n As Streng said himself, of the reaction of FOOF with sulfur tetrafluoride in perchloryl fluoride, ‘explosions could be avoided in some cases (at temperatures below 166 K) but the yield and stability of the intermediate product were very low.’. 0000065612 00000 n I’ve seen one reference to storing it as a solid at 90 Kelvin for later use, but that paper, a 1962 effort from A. G. Streng of Temple University, is deeply alarming in several ways. It can literally make ice catch fire. oxygen difluoride (plural oxygen difluorides) ( chemistry ) A binary compound of oxygen and fluorine , OF 2 ; a powerful oxidizing agent . 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. 0000004140 00000 n Though Streng was able to glean some information about elusive intermediates – mostly interhalogen species with pretty colours – it hardly seems worth it. O 2 F 2 precipitates as a brown solid upon the UV irradiation of a mixture of liquid O 2 and F 2 at -196 °C. 1st part: 1. Dioxygen Difluoride O2F2 Molar Mass, Molecular Weight. 0000002258 00000 n I. Dioxygen difluoride, J. Phys. 0000001015 00000 n 0000011274 00000 n Dioxygen difluoride (O 2 F 2) Dioxygen difluoride. Explosion. 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. While OF 2 would be a solid at 30 K, the fictional alien lifeforms were described as endothermic, maintaining elevated body temperatures and liquid OF 2 blood by radiothermal heating. 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. The structure of xenon difluoride is illustrated below. 588 OXYGEN DIFLUORIDE Irvine J. Solomon 10 W. 35th St., Chicago, IL 60616 The preparation and chemical and physical properties of the oxygen fluorides (OF2, OF, 02F2, OOF and 04F2) are reviewed. Molar Mass: 69.9956 :: Chemistry Applications:: You get the picture. Dioxygen difluoride can be obtained by subjecting a 1:1 mixture of gaseous fluorine and oxygen at low pressure (7-17 mmgHg is optimal) [citation needed] 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. For Example: respiration and combustion. This site uses cookies from Google and other third parties to deliver its services, to personalise adverts and to analyse traffic. One such compound is dioxygen difluoride, generally referred to as FOOF. ‘No other chemical,’ he writes in 1984, using italics for emphasis, ‘is capable of PuF6 generation at temperatures even approaching the low temperatures used here.’ He even patented the method that same year, highlighting how with this superior approach there is virtually no damage to the containment vessels – no doubt a rare and impressive selling point. <]>> 0000007116 00000 n In Robert L. Forward's science fiction novel Camelot 30K, oxygen difluoride was used as a biochemical solvent by fictional life forms living in the solar system's Kuiper belt. Can explode on contact with water. Dioxygen monofluoride. 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. 0000002777 00000 n Click on a star to rate it!
