Discussion Overview

The discussion centers around the possibility of oxidizing hydrofluoric acid (HF) to fluorine gas (F2) using only chemical oxidizing agents, without the application of electric energy or electrolytic cells. Participants explore historical methods and specific reactions related to this process.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether it is feasible to oxidize HF to F2 using only oxidizing compounds.
  • Another participant references Karl Christe's work from 1986, detailing a method that involves the abstraction of fluoride ions from MnF62- using SbF5, leading to the production of F2 gas through the decomposition of MnF4.
  • There is a request for the exact reaction involving the oxidation of HF, indicating a desire for clarity on the specific chemical processes involved.
  • One participant notes the complexity of multi-step processes, suggesting that it can be difficult to identify specific moments of reaction within an overall process.
  • Several participants express difficulty accessing the original article that contains the relevant reactions, leading to requests for sharing specific details from it.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the exact reactions or methods for oxidizing HF to F2, and there are multiple requests for clarification and specific details from the referenced article.

Contextual Notes

Some participants express limitations in accessing the original research document, which may hinder the discussion of specific reactions and details. The complexity of multi-step reactions is acknowledged but remains unresolved.

Is it possible to oxidate HF to F2 putting HF in contact with oxidizing compounds only, that is, without using electrolytic cells or, however, electric energy in general?
Thank you.

Karl Christe famously did this in 1986:

http://pubs.acs.org/doi/abs/10.1021/ic00241a001

His synthesis involves abstraction of two F- anions from MnF62- using two equivalents of the "fluorophile" SbF5. The stroke of genius here is that Christe recognized that MnF4 is thermodynamically unstable and decomposes into the stable MnF3 and F2 gas.

Thanks.
Which is the exact reaction involving the oxidation of HF?

Reactions 3,4 and 5 from the article
 
Note: in multi step processes sometimes its is impossible to pinpoint the moment when "something" happens, even when it is obvious from the overall reaction this "something" is what is done during the process.

Unfortunately I haven't access to that document. Would you please write them here?

You should at least see the first ppage of this article which contains all the formulas.

Yes, I can see it now, with the PC. With the smartphone I can't, don't know why.
