Hydrogen fluoride (fluorane) is an inorganic compound with chemical formula H F.It is a very poisonous, colorless gas or liquid that dissolves in water to yield hydrofluoric acid.
Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water.Solutions of HF are colorless, acidic and highly corrosive.A common concentration is 49% (48-52%) but there are also stronger solutions (e.g. 70%) and pure HF has a boiling point near room temperature.

Fluoroantimonic acid is the strongest superacid based on the measured value of its Hammett acidity function (H 0), which has been determined for various ratios of HF:SbF 5. The H 0 of HF is −15. [5] A solution of HF containing 1 mol % of SbF 5 is −20. The H 0 is −21 for 10 mol%. For > 50 mol % SbF 5, the H 0 is between −21 and −23.
Eurofins acquired MET Labs on 11 January 2018, which enabled the network to have a Nationally Recognized Test Laboratory as established by OHSA. [27] At the end of 2018, a deal was finalized between Eurofins and the JSTI Group for the acquisition of TestAmerica Environmental Services, LLC, adding 24 laboratories and 40 service centers to the ...
HF required quantity is in the range of 10–35 kg per ton of alkylate but most of the acid is recovered and recycled, so only a make-up is necessary to replace the consumed HF. In practice acid consumption in a SAAU is more than 100 times bigger than in a HFAU.
On August 28, 2022, Dentsply Sirona announced the appointment of Simon D. Campion, formerly Executive Vice President and President of the Interventional segment for BD, as President and Chief Executive Officer and a member of the board. [9] In 2018 a Netherlands-based certification company awarded Dentsply the “Top Employer” certification. [10]
Ammonium bifluoride, as its name indicates, contains an ammonium cation ([NH 4] +), and a bifluoride (or hydrogen difluoride) anion ([HF 2] −).The triatomic bifluoride anion features a strong three-center four-electron bond (specifically, a symmetrical hydrogen bond) with a bond energy greater than 155 kJ/mol, [2] and an H-F length of 114 pm.
