硝酸氧化蒽制备蒽醌

STUDIES ON OXIDATION OF ANTHRACENE TO ANTERAQUINONE BY NITRIC ACID

蒽醌是用途广泛的化工原料和中间体，主要用于生产还原染料、分散染料、活性染料和酸性染料等。此外，用蒽醌制造变性剂，可以保护植物种子，蒽醌还可用于制造双氧水。近几年来，蒽醌在纸浆制造方面的需求也在迅速扩大。目前，蒽醌的制造方法基本上可分为两种类型。一类是...

This paper provides a method of oxidizing anthracene to anthraquinone with nitric acid The effects of reaction time, temperature, nitric acid concentration and catalysts on anthraquinone yield are investigated Under optimum conditions, anthraquinone yield reaches 82 5% Because of its simplicity and mild condition, this method is convenient for preparing anthraquinone and thereby is prospective in industrial applicationS T U D I E S O N O X I D A T I O N O F A N T H R A C E N E T O A N T E R A Q U I N O N E B Y N I T R I C A C I D Chen Zhongxiu Peng Yaoli Wu Lin Wei Xianyong( Department of Energy Utilization and Chemical Engineering China Universityof Mining and Technology Xuzhou) Zong Zhimin( Open Research Laboratory of Com prehensive Utilization of Carbon Resources Dalian University of Technology Dalian) A B S T R A C T This paper provides a method of oxidizing anthracene to anthraquinone withnitric acid The effects ofreaction time ,temperature ,nitric acid concentration and catalystson anthraquinone yield are investigated Under optimum conditions , anthraquinone yieldreaches 825 %  Because ofits simpli
