Mellitic anhydride
Mellitic anhydride, the anhydride of mellitic acid, is an organic compound with the formula C12O9.
Mellitic anhydride is an oxide of carbon (oxocarbon), like CO2, CO, and C3O2. It is a white sublimable solid, apparently obtained by Liebig and Wöhler in 1830 in their study of mellite ("honey stone"); they assigned it the formula C4O3. The substance was properly characterized in 1913 by H. Meyer and K. Steiner. It retains the aromatic character of the benzene ring.
