The present invention relates to the technical field of bis-ether fluorene synthesis, in particular to a method for preparing bis-ether fluorene by catalysis of ethylene oxide. 0.25:1-0.35:1 ethylene oxide reacts with bisphenol fluorene in a polar organic solvent. In the preparation method of the present invention, ethylene oxide and bisphenol fluorene are used as synthetic raw materials, and alkali is used as a catalyst, and the reaction is carried out at normal temperature and pressure, and the cost of raw materials is low; the preparation method of the present invention does not generate waste gas and waste residue, and has little environmental pollution ; The preparation method of the present invention has simple process, low cost and is suitable for industrialized production. |
