An electrochemical process for the preparation of benzanthrones and planar, polycyclic aromatic oxygen-containing compounds is described. The process is carried out in an acid medium in an electrolytic cell which is separated by a diaphragm into a cathode compartment and an anode compartment. In the cathode compartment, anthraquinone or an anthraquinone derivative is reduced electrolytically to oxanthrone and the latter is reacted with glycerol to give the corresponding benzanthrone. In the anode compartment, a transition metal ion is simultaneously converted electrolytically from a lower oxidation stage into the next higher oxidation stage. The metal ion of higher valency is then used in the anolyte as an oxidizing agent by means of which the corresponding oxygen-containing compounds are obtained, starting from planar, polycyclic aromatic compounds.
本文介绍了一种用于制备苯并蒽醌和平面多环芳香氧化物的电化学过程。该过程在酸性介质中在电解池中进行,该电解池通过隔膜分为阴极室和阳极室。在阴极室中,蒽醌或蒽醌衍生物被电解还原为氧蒽酮,然后与甘油反应得到相应的苯并蒽酮。在阳极室中,过渡金属离子同时被电解从较低的氧化状态转化为下一个更高的氧化状态。更高价态的金属离子然后被用作氧化剂,从平面多环芳香化合物开始,得到相应的含氧化合物。
