Introduction:
Fluorene-9-bisphenol is an important organic chemical raw materials, mainly for the synthesis of polycarbonate, epoxy resin, polyester, polyether or polyether polycondensation products and other important monomer. Industrial fluorene-9-bisphenol from 9-fluorenone and phenol in the acid catalyst condensation reaction system, there are environmental pollution, corrosion and other shortcomings. Synthesis of fluorene-9-bisphenol using ion exchange resin as catalyst has good catalytic activity, mild reaction conditions, simple process, convenient operation, continuous production and high yield.
