Mellitic acid [C6(COOH)6] is the end product of the exhaustive oxidation of cokes, charcoals and carbon blacks, and of the controlled oxidation of many condensed cyclic hydrocarbons which contain benzene rings bearing six substituents (Ruof, Entel & Howard, 1956). Linear Formula C 6 (CO 2 H) 6. It crystallizes in fine silky needles and is soluble in water and alcohol. EC Number 208-243-6.

While there is agreement on the general features of the structure, my conclusions are different, and are that : … Our results showed a smooth gradient of mellitic acid concentration, being higher at the surface and near the surface (1.17–1.57 ppm) and diminishing with depth to be undetectable at a depth of 4 m. IN a recent communication, Bezjak and Grdenić 1 have described the crystal structure of mellitic acid (C 6 (COOH) 6 ). A benzene-derived hexacarboxylic acid in which each carbon of benzene carries a carboxy substituent. Molecular Weight 342.17 . Molecular Formula C 12 H 6 O 12; Average mass 342.169 Da; Monoisotopic mass 341.985931 Da; ChemSpider ID 2244 Molecular Formula. Brown, H.C., et al., in Baude, E.A. Stars This … Long digestion of the acid with an excess of phosphorus pentachloride forms the acid chloride, which crystallizes in needles, and melts at 190 °C. C12O9. Mellitic acid is a benzene -derived hexacarboxylic acid in which each carbon of benzene carries a carboxy substituent. For more information, see Help:SVG. It is decomposed, on dry distillation, into carbon dioxide and pyromellitic acid, C10H6O8; when distilled with lime it gives carbon dioxide and benzene. However, the mellitic acid containing six carboxyl groups (1,2,3,4,5,6-benzenehexacarboxylic acid) was used very rarely as building blocks for supramolecular synthesis [, , ]. Benzenehexacarboxylic trianhydride. The high stability of mellitic acid salts and their presence as an endproduct of the oxidation of polycyclic aromatic hydrocarbons, which are present in the solar system, make them a possible organic substance in Martian soil. Mellitic acid may be prepared by warming mellite with ammonium carbonate, boiling off the excess of the ammonium salt, and adding ammonia to the solution. I have also recently completed an independent and full refinement of the structure 2 . It crystallizes in fine silky needles and is soluble in water and alcohol. PubChem Substance ID 24896757.
