Introduction
(B) is a colorless crystal having blue fluorescence, and is green when dissolved in a concentrated sulfuric acid solution. The oxidation of hydrazine with chromic acid in a glacial acetic acid solvent affords the quinone, as the oxidation proceeds with the cleavage of the condensed ring to form a carboxylic acid, the final product being phthalic acid. Superconductivity is exhibited by the incorporation of potassium or rubidium between the layers of the Crystal cooled below 18K.
preparation
Picene is a polycyclic aromatic hydrocarbon of the chemical formula C22H14, obtained by distillation to dryness from the residue of Peat tar or petroleum distillation and Repeated recrystallization with p-isopropyltoluene.
