[edit] Cyclic aliphatic compounds

The article says, "aliphatic compounds are non-aromatic and non-cyclic". This requirement that it not be cyclic is consistent with sources such as Hampel, Glossary of Chemical Terms, 2nd edition (1992), page 11 and Hackh's Chemical Dictionary, 5th edition (1987), page 22. However, the IUPAC definition provided at IUPAC, Pure and Applled Chemistry, 67, 1307-1376 (1995), page 1313 says, "aliphatic compounds: Acyclic or cyclic, saturated or unsaturated carbon compounds, excluding aromatric compounds". Since IUPAC sets the standard in defining chemical nomenclature, and since their definition permits cycles, I question whether the Wikipedia definition should say "non-cyclic", and suggest that, at a minimum, it should state that the term is used sometimes with, and sometimes without, a bar on cycles.

I just stumbled on this page by chance and completely agree with your sentiments. Feel free to modify the article as you see fit. The joy of Wikipedia is that you can be bold and make these sorts of changes yourself without the bother of establishing consensus. :-) Best, David Iberri | Talk 21:37, 19 September 2005 (UTC)

This article contradicts the entry on alicyclic compounds http://en.wikipedia.org/wiki/Talk:Alicyclic_compound

I've corrected this blatant error. --Itub 08:14, 28 June 2007 (UTC)

[edit] Some questions

Hello I just wnated to add some questions: 1.What is the meaning of "aliphatic" compounds and where has this word been derived from? 2.Isn't it possible to "create" cyclic patterns of aliphatic compounds as well? If yes then why were cyclic compounds not considered as aliphatic? Aamil Syed Naeem, India 07/30/2006

"Due to it being a non-aromatic compound, aliphatic petroleum solvent is used as a starter for barbecues" Is it the toxicity that prevents using aromatic ones?... the why is not explained. - Ashi Starshade 21:20, 28 January 2007 (UTC)

I would like someone to clarify whether the term aliphatic can refer to non-aromatic cyclical compounds. As of August 13, 07 this article contradicts itself quite blatantly. Blocky 07:35, 13 August 2007 (UTC)
