White to tan powder or crystal or chunks | [Application]
9,9-Bis(4-hydroxyphenyl)fluorene can be used as a key monomer or intermediate in the synthesis of novel polyaryl ethers. In addition, bisphenol fluorene is sometimes used as an analytical reference standard in analytical chemistry for the quantitative detection of specific analytes. | [Definition]
ChEBI:9,9-bis(4-hydroxyphenyl)fluorene is a member of the class of fluorenes that is 9H-fluorene in which both of the hydrogens at position 9 have been replaced by p-hydroxyphenyl groups. It has a role as an anti-estrogen. It is a member of fluorenes and a polyphenol. | [General Description]
Bisphenol FL (BPFL) is a fluorinated derivative of bisphenol (BP), a wide group of chemicals with similar structures, recognized as environmental pollutants. Bisphenol A (BPA), and its structural analogs are widely used as plasticizers and monomers for synthetic materials, industrial and consumer products including fluorine rubber, food container linings, canned food, thermal receipts, etc. | [Synthesis]
Example 4 Synthesis of 9,9-bis-(4-hydroxyphenyl)-fluorene: 20 moles of phenol containing 9 wt. % water were stirred in an autoclave, followed by the addition of 1 mole of zinc chloride and 10 moles of fluorenone, which was allowed to dissolve. 5 moles of gaseous hydrogen chloride was passed into the stirred mixture and the reaction mixture was reacted at 70°C for 4 hours. Upon completion of the reaction, the mixture was dissolved in 5 liters of isopropanol at 60 °C. The resulting solution was poured into 10 times the volume of water under vigorous stirring to precipitate 3.4 kg of 9,9-bis-(4-hydroxyphenyl)-fluorene in 97% yield as a yellow solid. | [References]

| Questions And Answer | Back Directory | [The monomers and modifiers of functional polymer material]
9,9-Bis(4-hydroxyphenyl)fluorene is the monomer and modifier of functional polymer material,it is Cardo skeleton structure bisphenol compound, it is important monomer and modifier of synthesis of fluorene-based epoxy resin, fluorene and benzene benzoxazine resins, acrylic resins, polyester resins, polycarbonate, epoxy, polyester or polyether condensation products. Fluorene-based epoxy resin has excellent humidity resistance and heat resistance, dielectric properties, mechanical properties, chemical resistance, etc., it has been important monomer and modifier of high-performance resin matrix materials, electronic packaging materials, high temperature resistant adhesives, heat resistant coatings, etc. But the rigidity of fluorene-based epoxy resin is better, but toughness is poor, therefore, it need to be modified toughening when be used, or use the method of mixing with general-purpose epoxy resin to modify.
