All other trademarks and copyrights are the property of their respective owners. aHF Product information Characteristics Physical data Product specification Shipping information aHF etches sacrificial SiO₂ with very high selectivity in MEMS release etch of Si, poly-Si, and Al structural materials. This acid can be degraded to release HF thermally and by hydrolysis: In general, the anhydrous compound hydrogen fluoride is more common industrially than its aqueous solution, hydrofluoric acid. (In other words, one mole of hydrogen fluoride will weight approximately 20 grams. Dipoli acido fluoridrico.png 747 × 600; 140 KB. Contact Us Directly. Exposure requires immediate medical attention. just create an account. Pyrolysis of chlorodifluoromethane (at 550-750 °C) yields TFE. Molecular Formula: ClF 3: Synonyms: CHLORINE TRIFLUORIDE. This gives hydrogen fluoride a simple chemical formula of HF. Not to be confused with Fluorene, Fluoride, Fluorone, or Hydrogen fluoride. An important application of this reaction is the production of tetrafluoroethylene (TFE), precursor to Teflon. Chlorotrifluoride. Other metal fluorides are produced using HF, including uranium hexafluoride. It is a highly valuable molecule in industry, but is also a very dangerous chemical for biological systems. [14], HF reacts with chlorocarbons to give fluorocarbons. Therefore, hydrogen fluoride exposure is a serious issue. Hydrogen fluoride is a colourless gas with chemical formula HF. hydrogen fluoride formula Manufacturers Directory - find 61 hydrogen fluoride formula from hydrogen fluoride formula online Wholesalers for your sourcing needs from China. It is miscible, or will dissolve. One of our sales representatives will contact you. Auswirkung H-Brücke als Diagramm auf H-Verbindungen mit Lewis-Formeln.png 852 × 465; 52 KB. Hydrogen chloride is a gas, and has the formula HCl(g). The potassium bifluoride is needed because anhydrous HF does not conduct electricity. aHF offers high silicon dioxide etch selectivity over Si without stiction issues seen from wet etch process. 7790-91-2 . Hydrogen fluoride is a colourless gas with chemical formula HF. It is a polar covalent hydride . flashcard set{{course.flashcardSetCoun > 1 ? Finally, hydrogen fluoride is also a weak acid, meaning that if it is added to water, it will only partially break down and release hydrogen ions. 437 lessons Highly corrosive. Buy quality chemical formula of hydrogen fluoride products from chemical formula of hydrogen fluoride manufacturer, 27 chemical formula of hydrogen fluoride manufacturers & chemical formula of hydrogen fluoride suppliers from China. Remove and isolate contaminated clothing and shoes. [17], Upon contact with moisture, including tissue, hydrogen fluoride immediately converts to hydrofluoric acid, which is highly corrosive and toxic. It has an extremely acrid odor. HF reacts with Lewis acids to give superacids. It has many commercial uses, including oil production and uranium production. 61569264 jamesheilman-224x2991.jpg 2,592 × 1,936; 659 KB. Hydrogen fluoride is used primarily as a precursor or reactant for making other commercially important chemicals. Boils at 53°F. Hydrogen fluoride is a molecule that is formed from combining a hydrogen atom with a fluorine atom. This means that it will break down and destroy different materials on contact, including human skin and other organs. Dates: Modify . Reflecting the ability of HF to participate in hydrogen bonding, even proteins and carbohydrates dissolve in HF and can be recovered from it. The gas is 30% less dense than air (0.82 g L-1 at 25° and 1 atm (Lide, 2003)). A Hammett acidity function (H0) of −21 is obtained with antimony pentafluoride (SbF5), forming fluoroantimonic acid. credit by exam that is accepted by over 1,500 colleges and universities. H° − H° 298.15 = A*t + B*t 2 /2 + C*t 3 /3 + D*t 4 /4 − E/t + F − H. S° = A*ln (t) + B*t + C*t 2 /2 + D*t 3 /3 − E/ (2*t 2) + G. C p = heat capacity (J/mol*K) H° = standard enthalpy (kJ/mol) S° = standard entropy (J/mol*K) t = temperature (K) / 1000. Above room temperature, hydrogen fluoride is a gas, but can be condensed into solid crystals when the temperature is lower than roughly 20 degrees Celsius. Can initiate polymerization in certain alkenes. Quality chemical formula of hydrogen fluoride for sale from - 27 chemical formula of hydrogen fluoride - China chemical formula of hydrogen fluoride manufacturers from China. Log in or sign up to add this lesson to a Custom Course. It is present in a variety of over-the-counter products at concentrations of 6% to 12%. The process involves dehydrogenation of n-paraffins to olefins, and subsequent reaction with benzene using HF as catalyst. For example, in oil refineries "alkylate", a component of high-octane petrol (gasoline), is generated in alkylation units, which combine C3 and C4 olefins and iso-butane. © copyright 2003-2020 Study.com. You can test out of the Enrolling in a course lets you earn progress by passing quizzes and exams. Auswirkung H-Brücke als Diagramm auf H-Verbindungen.png 637 × 437; 29 KB. Perfluorinated carboxylic acids and sulfonic acids are produced in this way. Reacts exothermically with chemical bases (examples: amines, amides, inorganic hydroxides). Hydrogen fluoride is formed through covalent bonding (electron sharing) between a hydrogen atom and a fluorine atom. For example, hydrogen fluoride is often used to produce aluminum, which is a metal element. Most hydrogen fluoride is produced by reacting the mineral fluorspar (chemical formula CaF2) with sulfuric acid, but some may be produced from flu orosilicic acid which is a byproduct of the domestic phosphate industry or from industrial waste or recycled chemicals. HF is frequently used in the manufacturing of gasoline, refrigerants, herbicides, pharmaceuticals, and various other industrial applications. National Institute for Occupational Safety and Health, Ullmann's Encyclopedia of Industrial Chemistry, Facts About Hydrogen Fluoride (Hydrofluoric Acid), CDC - NIOSH Pocket Guide to Chemical Hazards, Hydrogen chalcogenides (Group 16 hydrides), https://en.wikipedia.org/w/index.php?title=Hydrogen_fluoride&oldid=991572318, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, colourless gas or colourless liquid (below 19.5 °C), Boiling points of the hydrogen halides (blue) and, This page was last edited on 30 November 2020, at 19:30.
