http://ntp-server.niehs.nih.gov/htdocs/8_RoC/RAC/TDI.html has a lot more information on toluene, and seems to be under the typical U.S. government copyright terms: not copyrighted unless it says otherwise. (A search on "copyright" shows 2 results, both of which contain an explicit notice of copyright.) I'm sending an email asking to make sure. --KQ

That page appears to be about toulene diisocyanate, not toulene. -- Simon J Kissane

Ah yes. C7H8, equally unpleasant but not the same thing. Thanks. --KQ

Well then copy it and make a new page.... -- mike dill

I'm waiting for a response about my copyright question.  :-) --KQ

I don't think you can make phenol out of toluene, removed it therefore. (well you could, but it would be foolish) Any reason why that was in there? I might be wrong (don't think so). Also added some synthetic uses. Also, Toluene (I work with it every day) is not that nasty, a lot less toxic than, say, benzene.Sikkema 23:27, 6 July 2007 (UTC)

[edit] toluene

toluene as rightly says is methyl benzene. the point the stucture of benzene has NO double bonds but a delocalised ring of electrons shown by the ring in the middle.

The Kekulé structure for benzene is universally accepted as a valid way of drawing an aromatic system- see any modern textbook of organic chemistry. Chemdraw has this form as the default. The "delocalised ring" presentation is valid and in some cases has advantages, but it is less used by organic chemists since it does not allow mechanisms to be drawn easily. Neither drawing fully represents the true structure. Walkerma 15:37, 13 May 2005 (UTC)
Why is methylbenzene not listed under "Other names" in the chembox? I'm adding it as this discussion page doesn't give a valid reason not to.--Redstar1916 22:16, 6 October 2007 (UTC)

The German Wikipedia has a very good article on this subject. It should probably be translated. →Iñgólemo← (talk) 00:47, 2004 Dec 9 (UTC)

[edit] Testing new chembox

Some of you may be puzzled by the sudden frantic (& sometimes bizarre!) editing going on this page- we are testing out a new Chemical infobox as part of the Chemicals Wikiproject. This should be completed soon. Walkerma 15:37, 13 May 2005 (UTC)

[edit] Delisted GA, delisted A-Class

This article was removed from the GA list due to lack of inline citations. Tarret 18:13, 14 March 2007 (UTC)

  • Citations now made inline, but peer-reviewer script output shows still deviations from A-Class article quality. Comments for improvement listed in the project template above. Tim Vickers, feel free to add. Wim van Dorst (Talk) 09:09, 21 March 2007 (UTC).

[edit] Metabolism

I haven't been able to find any references about toluene being transformed into epoxides. I have re-written this section to reflect the papers I could find that stated that benzaldehyde and cresols were the major products after benzyl alcohol. However, if this is correct, the diagram needs to be changed. What was the source for the original statement about epoxides? Also, dietary fiber is insoluble, but is excreted just fine in the feces, this sentence is unclear. TimVickers 00:50, 17 March 2007 (UTC)

Agreed. The second diagram also indicates benzaldehyde being oxidized to benzoic acid by the alcohol dehydrogenase, but I think that the acetaldehyde dehydrogenase would be the active catalytic site for that reaction. --148.163.78.11 22:56, 18 July 2007 (UTC)
Apparently the source is the German article, see here. Icek 03:50, 22 October 2007 (UTC)

[edit] GA review

Fail, several problems with the article.

  1. Non-encyclopedic tone - "Around 25 times more reactive" "Undergoes smooth sulfonation"
  2. The "Uses" section is a jumble of factoids that has too much emphasis on motor racing
  3. In "metabolism" section important facts unreferenced and diagram appears to be incorrect (see above)
