| titleOfInvention | A kind of preparation method of 9,9-bis[4-(2,3-glycidoxy)phenyl]fluorene |
| abstract | The invention belongs to the technical field of epoxy resin synthesis, and discloses a preparation method of 9,9-bis[4-(2,3-glycidoxy)phenyl]fluorene. The steps are: S1: adding 9- Fluorenone, co-catalyst and modified carrier catalyst are added to the solvent, stirred and reacted, and purified to obtain bisphenol fluorene; S2: the bisphenol fluorene and epichlorohydrin are stirred and reacted under alkaline conditions, and purified to obtain 9,9-bis[4-(2,3-glycidoxy)phenyl]fluorene. The synthesis route of the invention is simple, the reaction is easy to handle, the pollution in the production process is small, the corrosion is small, and the product yield is high. |
