Talk:Pentane
From Wikipedia, the free encyclopedia
The link to fluid properties in webbook.nist.gov/chemistry should be made. Comments on colour, odor and provenance should also be made. Common uses as well as history.
Add a link to the korean physical properties database and comment on the differences between n-pentane, isopentane and cyclopentane.
[edit] Poor ole pentane
Trying to think of something to say about this drab little molecule.
- from the comments above - pentane has only the faintest odor, possibly that is due to trace impurities?
- It probably undergoes dehydrocyclization in refineries.
- It would also be nice to know the C5 content in crude oils as well as typical petroleum fractions, e.g. gasolines.
- Pentanes are purification from NaK?
- isopentane makes a glass at low T, I have heard.
- neopentane can be viewed as an expanded form of methane, whereby each of the four H's are replaced by Me. I guess that next generation in such bare-bones dendrimers, i.e. C(CMe3)4 would be too crowded.
- regiochem of free radical chlorination would be worth while?
- butane is convertable via VOPO4/O2 into maleic anhydride, I think, but I dont know if pentane does that.

- We could do with a hand from synthetic organic colleagues here: why would anyone choose to use pentane in the lab? Physchim62 (talk) 11:57, 6 March 2006 (UTC)
Where I am, ambient temperature is ~ 30 °C so we usually use hexane. But we had some exchange people from Germany who liked to use it instead of hexane for usual laboratory tasks like wiping ground glass joints to remove grease. I've used it (following a literature procedure) for liquid-liquid extraction before, but that's about it. --Rifleman 82 09:16, 9 August 2007 (UTC)

- I have heard a really strange tale that hexane is converted to hexane dicarboxylic acid in the body and due to its length it is incorporated into the DNA and because of this better use pentane or cyclohexane in the lab. I do n ot belive it and I also found no proof of it in any article, but some people belive this.
Lower boiling point maks it convenient if you extract something with a low boiling point. And it is better for deep temperature mixtures than hexane.--Stone 12:34, 9 August 2007 (UTC)
[edit] Functional
The words "unfunctionalized" and "functionality" are used in the section on Uses, and the latter is linked, but the link doesn't give you any information about the use of functionality in the context of hydrocarbons.

- disambiguated to functional group, and also added the link to the function page (might need a bit of a rewrite of the definition on the latter). Hope this helps, and cheers for bringing this to our attention. --Dirk Beetstra T C 20:08, 17 December 2006 (UTC)
