Antimony Pentafluoride is a water insoluble Antimony source for use in oxygen-sensitive applications, such as metal production. More info about absorbents, including situations to watch out for... National Oceanic and Atmospheric Administration. Olah, G. A.; Prakash, G. K. S.; Wang, Q.; Li, X.-y. Uses: (a) It is used as a refrigerant (cooling agent) in refrigerators and air conditioners. It is notable for its Lewis acidity and its ability to react with almost all known compounds. Fumes irritate the eyes and mucous membranes. The antimony pentafluoride is separated from the volatile byproducts by fractional distillation. Using crossed seeded nozzle beams we have examined the energy dependence of the cross section for the reaction SbF 5 +RX→SbF 5 X - +R + , where X is a halogen and R an organic radical. absorbents *Please select more than one item to compare Web site owner: Warning: Antimony Pentafluoride is highly corrosive to the eyes, skin, and lungs, and is extremely toxic if swallowed.

Tetra(trifluoromethyl)-1,3-diselenetane (19) is oxidized by the Lewis acid antimony pentafluoride to give the selenium-centered radical cation (53) as a deep blue solution 〈91JFC(53)71〉. listed below. What is the percent composition of Sb in this molecule - 18916627 Having a look I'd say the lowest Hammett value I could find would be H = -20 for magic acid or 'a 1:1 molar ratio, of fluorosulfuric acid (HSO3F) and antimony pentafluoride (SbF5)'. When heated to decomposition, it emits highly toxic fumes of fluorides and metallic antimony. [SbF6]− is a weakly coordinating anion akin to PF6−. & indicates that no RQ is assigned to this generic or broad class, although the class is a CERCLA hazardous substance. Chemistry Q&A Library Antimony pentafluoride (SbF5), reacts with XeF4 and XeF6 to form ionic compounds XeF3+SbF6− and XeF5+SbF6−. Contact with eyes or skin causes severe burns. "Development of the Table of Initial Isolation and Protective Distances for the 2008 Emergency Response Guidebook", ANL/DIS-09-2, D.F. Dichloro difluoro methane (Freon 12) is the most common freons. Chemical waste generators must also consult local, regional, and 13. The carborane superacids may be considered the world's strongest solo acid, as fluoroantimonic acid is actually a mixture of hydrofluoric acid and antimony pentafluoride. The antimony electrode is simply a piece of pure antimony rod (~12 mm diameter, 140 mm long), housed in a protective plastic body resistant to acid attack; see Figure 24.25.The protruding antimony rod, when immersed in a solution containing dissolved oxygen, becomes coated with antimony trioxide Sb 2 O 3, and the equilibria governing the electrode potential are Office of Response and Restoration, The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. Toxic. Edwards, A. J.; Taylor, P. "Crystal structure of Antimony Pentafluoride" Journal of the Chemical Society, Chemical Communications 1971, pp. It is brought into this country from other countries for processing. Reacts vigorously with bases. Belongs to the Following Reactive Group(s). Search results for 7783-70-2 at Sigma-Aldrich.

Hazardous polymerization may not occur. BiF5 is a polymer. Describe the geometries of the cations and anion in these two compounds. It is notable for its Lewis acidity and its ability to react with almost all known compounds. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. *Please select more than one item to compare. The compound is extremely toxic with a probable oral lethal dose of 5-50 mg/kg or between 7 drops and one teaspoonful for a 150 pound person (antimony salts). Antimony is a silvery-white metal that is found in the earth's crust. [6], In the gas phase, SbF5 adopts a trigonal bipyramidal structure of D3h point group symmetry (see picture). Salts, basic, such as ANTIMONY LACTATE, are generally soluble in water. Advanced Search | Structure Search. It can also be prepared by allowing fluorine to react with antimony powder or molten antimony trifluoride. The crystalline material is a tetramer, meaning that it has the formula [SbF4(μ-F)]4. Antimony pentafluoride, (SbF5), with hydrofluoric acid (HF), produces an acid with a pH of -31. Antimony pentafluoride is the inorganic compound with the formula SbF 5. Although it is only weakly basic, [SbF6]− does react with additional SbF5 to give a centrosymmetric adduct: SbF5 reacts violently with many compounds, often releasing dangerous hydrogen fluoride. Its chief use is the fluorination of organic compounds. SbF 5, most commonly known as Magic acid, is produced by mixing fluorosulfuric acid and antimony pentafluoride in a molar ratio of 1:1. This colourless, viscous liquid is a valuable Lewis acid and a component of the superacid fluoroantimonic acid, the strongest known acid formed when mixing liquid HF with liquid SbF 5 in a 2:1 ratio. Clean Air Act: CAS# 7783-70-2 (listed as Antimony compounds) is listed as a hazardous air pollutant (HAP).
