(57) Abstract: A novel method for producing 9,9-bis (4- (2-hydroxyethoxy) phenyl) fluorene. An M n + x / n (Al 4-x Mg x) Si 8 O 20 (O H) 4 .yH 2 O (1) wherein M represents a metal atom or a hydrogen atom, and 0 <x < 4, n represents a positive integer, and y is 0 or more. Fluorenone in the presence of a catalyst wherein M n + present between the layers of montmorillonite represented by the formula is ion-exchanged with one or more cations of an element selected from the group consisting of aluminum, titanium, iron, tin, tungsten and copper. Reacting phenoxyethanol with 9,9-bis (4- A method for producing (2-hydroxyethoxy) phenyl) fluorene. |
