| titleOfInvention | Method for purifying 9,9-bis (4-hydroxyphenyl) fluorene |
| abstract | (57) [Abstract] [Purpose] Crude 9,9-bis (4-hydroxyphenyl) Fluorene is purified to a purity of 99.8% or more with a recovery of 80% or more. [Structure] Crude 9,9-bis (4-hydroxyphenyl) Fluorene is completely dissolved in acetate at room temperature, This is a purification method in which an aliphatic hydrocarbon solvent such as hexane is added to precipitate crystals. The precipitated crystals are separated by filtration, and if necessary, the above operations are repeated, and finally dried at 100 to 150 ° C to obtain a product. [Effects] Crude 9,9-bis (4-hydroxyphenyl) fluorene can be easily purified with a high recovery rate by a simpler means than the conventional method, which is industrially extremely advantageous. |
