The production of 9-fluorenone at home and abroad is still dominated by the catalytic oxidation of fluorene. With the continuous expansion of the application field of fluorenone, the quality of fluorenone produced by traditional liquid phase oxidation has been difficult to meet the requirements of many functional material industries.
The development of low-cost, high-yield, non-polluting or less-polluting methods to prepare high-quality 9-fluorenone will attract widespread attention.
