Talk:Hexafluoroacetone

of hydrogen gas

I deleted the hydrogen because the hydrogen has to come from nowhere, because there is no hydrogen in the metal nor in the Hexafluoroacetone.Stone 08:20, 3 March 2006 (UTC)[reply]

Hi Stone, I found that piece of information in a MSDS document for hexafluoroacetone under the "stability & reactivity" section (#10):(http://www.airliquide.com/safety/msds/en/063_AL_EN.pdf). Honestly I can't vouch for its rightness and I agree with you that if hydrogen is formed in those conditions it will come from neither the HFA, nor the metal. May it be coming from the moisture? If you have or find evidence that claim is wrong feel free to remove it.

Hi Berserker79 the moisture mentioned in the paper has to go into the article, because the hydrogen source has to be mentioned. In chemical experiments under inert atmosphere only HF will form. So if the moisture is in everything is OK.

hexafluoroacetone can hydrolyse and produce hydrogen fluoride, which can react with metals to produce the fluoride salt of the metal and hydrogen.

the diagramm is also wrong, since the left image is of 2-oxo-1,1,1,3,3-pentafluoride butan. one of the lines is missing the F for fluoride at the end. --Weeddude 17:24, 21 October 2007 (UTC)[reply]

The original image which is correct has been restored. --Ed (Edgar181) 15:24, 17 November 2007 (UTC)[reply]

HFA is inorganic

To be (annoyingly?) precise, hexafluoroacetone is not organic and should be listed as an inorganic stub.--Smokefoot 13:25, 3 June 2006 (UTC)[reply]

please explain why this is not an organic compound? --Weeddude 17:27, 21 October 2007 (UTC)[reply]

Often (or usually, depending on where you are from), an organic compound contains C-H bonds. Thus carbon disulfide, carbonate, and hexafluoroacetone would not qualify. Many chemists would say that the rule is too strict and that one can intuitively identify an organic compound by looking at the structure. You can see that WE-chem currently defines organic compound as only having carbon. --Smokefoot 20:23, 21 October 2007 (UTC)[reply]

sorry, that is not quite complete. organic compounds are those compunds that contain C-H bonds or are derived from such compounds. this means that carbon sulfide and carbonate are not, since these are derived from inorganic substances, but acetone and hexafluoraceteon are. By your definition Tetrafluoroethylene would not be organic either. please check the WE entry for organic chemistry for more information.

you are right though that the definition is not universally consistent. Weeddude (talk) 08:25, 17 November 2007 (UTC)[reply]

Not that I am losing any sleep over this but CS2 is mainly made from CH4, as I recently discovered: CH4 + 4 S --> CS2 + 2 H2S--Smokefoot (talk) 15:12, 17 November 2007 (UTC)[reply]

Any "rule" that would exclude urea and uric acid as organic molecules is bollocks IMO. The only distinction is conventional; most of the inorganic carbon containing compounds are classified as inorganic only for historical reasons dating from the 19th century. I don't think many people would seriously consider hexafluoroacetone inorganic, as it is seen as an acetone derivative rather than an "inorganic" substance of "non-living" origin (as is the case with carbonates, for example). --Itub (talk) 10:31, 18 November 2007 (UTC)[reply]

HFA IS ORGANIC! By IUPAC, an organic compound is a functionalized hydrocarbon. In this case acetone is a functionalized compound of propene. And HFA is functionalized drom acetone. IT IS ORGANIC! NOT ALL organic compounds contain H! Nergaal (talk) 22:55, 26 November 2007 (UTC)[reply]

glad we settled that. Weeddude 17:50, 1 December 2007 (UTC)[reply]

Why SESQUIhydrate?

The article says that "The most common form of this substance is hexafluoroacetone sesquihydrate (1.5 H2O), which is a geminal diol." To be precise, the geminal diol would be the MONOhydrate. The sequihydrate must be a hemihydrate of the geminal diol: ((F
₃C)
₂C(OH)
₂) · 0.5(H
₂O). Correct? --Jorge Stolfi (talk) 07:08, 30 May 2018 (UTC)[reply]

Maybe HO-C-O-C-OH?--Smokefoot (talk) 13:09, 30 May 2018 (UTC)[reply]
