The process yield of preparing 9-fluorenone from non-fluorene raw materials is high, and the product quality is good. However, due to the high cost of raw materials and the complicated synthesis route, the production of 9-fluorenone at home and abroad is still based on the catalytic oxidation process of fluorene. the Lord. With the continuous development of the application field of 9-fluorenone, the quality of fluorenone produced by traditional liquid-phase oxidation method has been difficult to meet the needs of many functional materials industries. The development of low-cost, high-yield, pollution-free or less-polluting methods to prepare high-quality 9-fluorenone will attract widespread attention.
