Liebig and Wohler ?
[edit]There is a 1830 paper by Liebig and Wohler (see below) that appears to describe or hypothesize a compound distilled from mellite ("honeystone", "Honigstein") with empirical formula C4O3 (which happens to be 50:50 C:O by mass!). There is also a 1848 review by Erdmann and Marchand that apparently confirms their analysis. I suppose that "C4O3" is the same mellitic anhydride that Meyer and Steiner characterized in 1913. But I cannot really read German, so I would appreciate if someone could check that. Thanks, and all the best, --Jorge Stolfi (talk) 07:43, 9 July 2009 (UTC)

TMA is an extreme sensitizer. Shouldn't something be said about that? 174.46.159.253 (talk) 20:45, 29 November 2010 (UTC)
Trimellitic anhydride vs Mellitic (tri)anhydride
[edit]I think that Trimellitic anhydride and Mellitic (tri)anhydride may have been mixed up in this topic. These have different structures. While the structure of Mellitic (tri)anhydride is presented, the reference for the melting point of 161C refers to Trimellitic anhydride. 139.63.194.173 (talk) 15:33, 20 July 2023 (UTC)
