Useful:

• Chemical Classes: Toxic Gases & Vapors -> Other Toxic Gases & Vapors
• Canonical SMILES: F[Sb](F)(F)(F)F
• Inhalation Risk: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: Corrosive. Inhalation may cause severe swelling of the throat. This may result in asphyxia. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. Exposure at high levels could cause severe lung damage. Medical observation is indicated.
• Effects of Long Term Exposure: The substance may have effects on the cardiovascular system and respiratory tract. This may result in impaired functions.
• Physical properties: Colorless oily liquid; highly viscous; hygroscopic; freezes at 8.3°C; boils at 149.5°C; density 2.99 g/cm3 at 23°C; soluble in excess water (with violent reaction) and glacial acetic acid; also soluble in potassium fluoride.
• Uses: HF/SbF5 is an excellent medium for the preparation of alkylidene oxonium salts.1 In the fluorination of organic Compounds, see the monograph Preparation, Properties and Technology of Fluorine and Organic Fluoro Compounds, C. Slesser, S. R. Schram, Eds. (McGraw-Hill, New York, 1951) 868 pp.

Technology Process of Antimony pentafluoride

There total 46 articles about Antimony pentafluoride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 90.0%

antimony (7440-36-0) + trifluoroamine oxide (13847-65-9,57526-95-1,478286-98-5) → antimony pentafluoride (7783-70-2)
