    • PURPOSE: A method for synthesizing aromatic quinones and ketone through oxidation process of aromatic compounds in organic solvent containing nitric acid solution as catalyst is provided to produce aromatic quinones and ketone with high purity/yield rate, and also organic solvent and nitric acid solution used can be effectively recovered for recycling. CONSTITUTION: The preparation method comprises oxidizing aromatic compounds such as anthracene, fluorene and diphenylmethane with oxygen in an organic solvent containing nitric acid solution of 30 to 80% in an autoclave at the oxygen pressure of 0.1-5.0 atm., at 70-150°C for 1-3 hours. Organic solvent is one or more than one selected from halobenzene, nitrobenzene, alkylbenzene, C1-C10 organic acids. The nitric acid solution used is in an amount of 0.1-2.0wt.% to the aromatic compound. During the reaction, oxygen is fed continuously to keep the reaction pressure between 0.1 and 5.0 atm. The method is characterized in that the used organic solvent and nitric acid solution can be recycled 1-15 times.
    • 目的:提供芳香族化合物在含硝酸溶液作为催化剂的有机溶剂中通过氧化工艺合成芳香醌和酮的方法,以高纯度/高产率制备芳香醌和酮,还可使用有机溶剂和硝酸溶液 有效回收利用。 构成:制备方法包括在0.1-5.0大气压的氧气压力下,在70〜150℃的高压釜中,在含有30〜80%硝酸溶液的有机溶剂中,用氧氧化芳香族化合物如蒽,芴和二苯基甲烷 C 1-3小时。 有机溶剂是选自卤代苯,硝基苯,烷基苯,C 1 -C 10有机酸中的一种或多种。 硝酸溶液的用量为芳族化合物的0.1-2.0重量%。 在反应期间,连续供给氧气以保持反应压力在0.1和5.0atm之间。 该方法的特点是使用有机溶剂和硝酸溶液可回收1-15次。
