Talk:Furan

I don't understand the part "in a similar way to which a carbon-carbon double bond is in benzene". What is the omitted verb after "is"?

I think it means there is a carbon-carbon double bond in Benzene, similar to the one in Furan. Of course I don't know what any of that means.

The structures are mislabelled as tetrahydrofuran

Furan is certainly not aromatic. The doubles bonds are only conjugated. See Huekel's Rule.
 * Furan is aromatic - two double bonds plus one of the two lone pairs from the oxygen atom meet Huckel's rule. --Ed (Edgar181) 11:29, 27 July 2006 (UTC)

Furan in soy protein
Furan's presence in soy protein should be mentioned in the article. Badagnani (talk) 07:25, 30 December 2007 (UTC)

Usage
Can someone add a usage section to this article?Patcat88 (talk) 04:44, 12 April 2008 (UTC)

Really, Can someone add a usage section to the article? Why is the compound noteworthy? Aflafla1 (talk) 02:34, 15 June 2011 (UTC) Someone needs to add a usage section!!!!!!!!!!!!!!!!

The main use of furan is as a chemical intermediate. That is noted in the lede section. It is also the title compound of a class. Apart from that, Ullmann's doesn't indicate that it's an exceedingly important compound. I've removed the recent additions because dibenzofurans are not furan. At best, they have the furan ring structure, but fused to benzene rings, making them quite different. --Rifleman 82 (talk) 19:36, 13 August 2012 (UTC)

Reactivity
Would I be correct in guessing that one reason why furan is more reactive than benzene is the positive charge on the oxygen atom that is seen in four of the five resonance structures? Hellbus (talk) 08:40, 7 September 2009 (UTC)

Furan and the HEATOX Project
I see nothing about the HEATOX (Heat-generated Food Toxicants) Project and its mention of Furan. According to the HEATOX Project... "Acrylamide is not the only genotoxic compound formed when heating food. Furan, HMF and other compounds have been investigated. A database of more than 800 heat-induced compounds, of which around 50 have been highlighted as potential carcinogens based on their chemical structure, has been compiled to aid future research." http://www.slv.se/upload/heatox/documents/Pressrelease_HEATOX_project_completed_%E2%80%93_brings_new_pieces_to_the_Acrylamide_Puzzle.pdf prsglenn (talk) 18:14, 16 January 2011 (UTC)

Check the Flash point
I think flash point should be -35°C atleast in every finnish source the flash point is said to be 35°C

http://fi.wikipedia.org/wiki/Furaani (leimahduspiste - 35 °C) http://kappa.ttl.fi/kemikaalikortit/khtml/nfin1257.htm (Leimahduslämpötila: -35°C)

Toxicity
The lead says that Furan is toxic but I can find no detail or reference.
