Anhydride?

I wonder whether this acid forms an anhydride (C9H6O6 = C9O3 + 3H2O)? That would be another oxocarbon... --Jorge Stolfi (talk) 02:51, 16 November 2009 (UTC)[reply]

Interesting question. C9O3 wouldn't really be an acid anhydride, but rather a benzene fused to three cyclopropanones. It would be highly strained, and if it can be made at all, I don't think it would be by dehydration of trimesic acid. On the other hand, it might be possible to form a polymeric anhydride, but that wouldn't be an oxocarbon because the C-H bonds would remain (those hydrogens are not easily removed by dehydration). --Itub (talk) 20:53, 16 November 2009 (UTC)[reply]

I found another paper where this hypothetical oxocarbon is discussed. IIRC, they note that it would probably isomerize to what they call carbo[3]oxocarbon, a triangle with the three O's at the corners and three -C-C≡C-C- sticks for sides. They also discussed carbo[n]oxocarbons for higher n which should be less strained. Unfortunately I lost the URL. I don't know whether any had been made. All the best, --Jorge Stolfi (talk) 02:34, 17 November 2009 (UTC)[reply]

Further data?

Melting point/boiling point/production methods? NFPA 704, too.
