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. "Mellitic Acid". The synthesis of mellite from mellitic acid, KOH and Al2(SO4)3•18H2O is demonstrated and discussed as a potential geomimetic process for the formation of the mineral mellite in brown coal. COVID-19 is an emerging, rapidly evolving situation. Mellitic Acid Synthesis and Properties I heard about this acid a long time ago, and suddenly remembered about it, with a sudden urge to make it and test its properties. The hexachloride of mellitic acid has been prepared in the pure state. It is decomposed, on dry distillation, into carbon dioxide and pyromellitic acid, C10H6O8; when distilled with lime it gives carbon dioxide and benzene. The ammonium salt is then converted into the lead salt by precipitation with lead acetate, and the lead salt is then decomposed by hydrogen sulfide. Citing Literature. Sigma-Aldrich offers abstracts and full-text articles by [Kathryn G Rose, Deana M Jaber, Dina A Jaber, Chenaimwoyo A Gondo, Darren G Hamilton]. The ammonium salt is then converted into the lead salt by precipitation with lead acetate, and the lead salt is then decomposed by hydrogen sulfide. p. 95.

Mellitic acid | C12H6O12 | CID 2334 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Molecular Weight 342.17 . 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. Long digestion of the acid with an excess of phosphorus pentachloride forms the acid chloride, which crystallizes in needles, and melts at 190 °C. and Nachod, F.C., Kurmoo M, Estournes C, Oka Y, Kumagai H, Inoue K (2005) Inorganic Chemistry volume 44, page 217, Proceedings of the National Academy of Sciences, https://en.wikipedia.org/w/index.php?title=Mellitic_acid&oldid=963942230, Articles with dead external links from January 2018, Articles with permanently dead external links, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Wikipedia articles incorporating a citation from the 1911 Encyclopaedia Britannica with Wikisource reference, Wikipedia articles incorporating text from the 1911 Encyclopædia Britannica, Creative Commons Attribution-ShareAlike License, This page was last edited on 22 June 2020, at 17:46. D. Appleton and Co. (1889). Linear Formula C 6 (CO 2 H) 6. We investigated the directions of Maumené‐Lecuir, for preparing the potassium salt of mellitic acid by thermal decomposition of the potassium salt of tartaric acid; we obtained only very low yields of mellitic acid by this method. EC Number 208-243-6. Mellitic acid, also called graphitic acid or benzenehexacarboxylic acid, is an acid first discovered in 1799 by Martin Heinrich Klaproth in the mineral mellite (honeystone), which is the aluminium salt of the acid. NACRES NA.22 If you do not receive an email within 10 minutes, your email address may not be registered, [4] It crystallizes in fine silky needles and is soluble in water and alcohol.

We investigated the directions of Maumené‐Lecuir, for preparing the potassium salt of mellitic acid by thermal decomposition of the potassium salt of tartaric acid; we obtained only very low yields of mellitic acid by this method. [6], Mellitates (and salts of other benzene polycarboxylic acids) of iron and cobalt have interesting magnetic properties.[7]. The acid may also be prepared by the oxidation of pure carbon, graphite or hexamethylbenzene, by alkaline potassium permanganate in the cold, or by hot concentrated nitric acid.[5].

Mellitic anhydride, the anhydride of mellitic acid, is an organic compound with the formula C 12 O 9. 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. The mixture may be separated by dissolving out the ammonium euchroate with water.
