Mellitic acid reactions

Mellitic acid

Mellitic acid crystallizes in accomplished cottony all-overs and is acrid in baptize and alcohol. It is a actual abiding compound; chlorine, concentrated nitric acid and hydriodic acid do not acknowledge with it. It is decomposed, on dry distillation, into carbon dioxide and pyromellitic acid, C10H6O8; if distilled with adhesive it gives carbon dioxide and benzene. Long assimilation of the acid with an balance of phosphorus pentachloride forms the acid chloride, which crystallizes in needles, and melts at 190 °C. By heating the ammonium alkali of the acid to 150–160 °C while ammonia is evolved, a admixture of paramide (mellimide, atomic blueprint C6(CONHCO)3), and ammonium euchroate is obtained. The admixture may be afar by abandoning out the ammonium euchroate with water. Paramide is a white baggy powder, baffling in baptize and alcohol.
The top adherence of mellitic acid salts and their attendance as an endproduct of the blaze of polycyclic ambrosial hydrocarbons, which are present in the solar system, accomplish them a accessible amoebic actuality in Martian soil.
Mellitates (and salts of added benzene polycarboxylic acids) of adamant and azure accept absorbing alluring properties.
