9,9-Bis(Hydroxyphenyl)Fluorene

Introduction:

9,9-Bis(Hydroxyphenyl)Fluorene 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 9,9-Bis(Hydroxyphenyl)Fluorene from 9-fluorenone and phenol in the acid catalyst condensation reaction system, there are environmental pollution, corrosion and other shortcomings. Synthesis of 9,9-Bis(Hydroxyphenyl)Fluorene using ion exchange resin as catalyst has good catalytic activity, mild reaction conditions, simple process, convenient operation, continuous production and high yield

Specification:

9,9-Bis(Hydroxyphenyl)Fluorene, molecular formula C25H18O2, a molecular weight of 350.4, it is a white powdery substance, the melting point of 222-224 ° C

Package

The package of all our chemical products reaching up to the industry standard, we usually use kraft drums or woven bags for our powder state products.

Application:

With 9,9-Bis(Hydroxyphenyl)Fluorene prepared polyether products, the glass transition temperature is greatly improved, greatly improving the thermal stability of polyether and heat resistance, 9,9-Bis(Hydroxyphenyl)Fluorene modified polyether can also be used to prepare transparent conductive film, orientation Membrane, gas separation membrane and so on.

Its transparency,Refractive index has increased,Can be used for manufacturing Optical Instruments
