Talk:Organic acid anhydride

Acetic acid
Acetic acid CAN form an ester with a phenol. Though, it wont become an irreversible reaction (which is the case with acid anhydrides).

Taking this article to absurd limits?
I was going to stick something like this in the article and then I realized that it is kinda crazy. It would be nice to figure out a way of describing mixed anhydrides without describing all matter!

Classically, mixed anhydrides arise from the dehydration of two different oxy acids:
 * 2 XOH +  YOH  &rarr;  XOY  +  H2O

Again, in principle, this conversion could desribe the formation of a large number of binary oxides.
 * Example:
 * HNO2 +  H2SO4  &rarr;  ONHSO4 ( = ONOSO2OH)  +  H2O

The scope of the mixed anhydrides is even greater when one considers the possibility of one of the acids not being an hydroxyl acid.
 * XOH +  YH  &rarr;  XY  +  H2O


 * Example:
 * HNO2 +  HCl  &rarr; NOCl  +  H2O

This analysis suggests that all chemical compounds could in fact be described as acid anhydrides. --Smokefoot 23:50, 24 September 2006 (UTC)
 * I'm not sure how to respond to this. You should look at the article on inorganic acidic anhydrides (if you're still reading Wikpedia). Shalom (Hello • Peace) 22:25, 13 December 2007 (UTC)

Definition is too narrow?
I had the vague idea (from high school chemistry) that an anhydride was "an acid minus one or more H2O's". That definition is obviously too general, but the one given in the article seems too narrow. For example, maleic anhydride and mellitic anhydride do not fit the diagram given. At a minimum, the definition must be modified to allow those "self-anhydrides".

 * I thought it was fine about four years ago, but some guy changed it all around to concentrate only on the organic part. Despite what some people may think, there's no conflict in definition between organic and inorganic chemistry. —Preceding unsigned comment added by 208.2.172.2 (talk) 20:52, 27 October 2009 (UTC)

I agree. There should at least be an explanation (even though this will be repeated from the article on anhydrides) of what the name means. Firezdog (talk) 04:10, 16 January 2011 (UTC)


 * there is no article on anhydrides, someone changed it to redirect —Preceding unsigned comment added by 70.180.238.179 (talk) 01:23, 27 January 2011 (UTC)
