(57) Abstract: The object of the present invention is suitable for industrial practice, The present invention also provides an economically advantageous method for producing a fluorene derivative, that is, a method for industrially advantageously producing 9,9-bis (4- (2-hydroxyethoxy) phenyl) fluorene with high quality and high yield. It is in. SOLUTION: Fluorenone is reacted with phenoxyethanol using sulfuric acid and thiol as a catalyst to obtain 9,9. In the method for producing -bis (4- (2-hydroxyethoxy) phenyl) fluorene, the following conditions (1), (2) and (3) are used as a reaction solvent (1) It is hardly compatible with water (2) (3) Production of a fluorene derivative, characterized by using an organic solvent which simultaneously satisfies that the desired 9,9-bis (4- (2-hydroxyethoxy) phenyl) fluorene is easily dissolved.
