Is it possible to remove water from a 40% HF aqueous solution to obtain anhydrous HF?
Thread Content
I would like to ask if there is a process for removing water from HF azeotropes (HF and water) in order to obtain anhydrous HF
Distillation: By heating water to 50 degrees, HF is obtained
Hydrofluoric acid forms an azeotrope, so direct distillation cannot yield anhydrous hydrogen fluoride.
In the dehydration of hydrofluoric acid to produce hydrogen fluoride, an important step is to retain water at the bottom of the distillation tower.
Is it because hydrofluoric acid and water form hydrogen bonds? There is a process for producing anhydrous form, but I have never seen a process for separating anhydrous hydrofluoric acid through distillation.

Concentrated sulfuric acid or 105% should work
The azeotrope point of hydrofluoric acid is above 35%, and it is not possible to obtain anhydrous hydrofluoric acid through azeotropy
