Product Description

9-fluorenone Basic information

9-FLUORENON;9-FLUORENONE;9H-FLUOREN-9-ONE;FLUORENONE;FLUORENONE(9-);FLUOREN-9-ONE;AURORA KA-7498;9-Fluorenone/9H-Fluoren-9-one9-fluorenone is an important intermediate for organic synthesis. It can be used to manufacture a variety of fine chemicals, mainly used as a modifier for the production of polymer materials, bisphenol fluorene, fluorenyl benzoxazine resin, acrylic resin, polyester, polycarbonate and epoxy resin. In the laboratory, fluorene was used as the raw material, dimethyl sulfoxide as the solvent, sodiu m hydroxide as the catalyst and oxygen as the oxidant. The oxidizing reaction was carried out by a tower packing reactor. The reaction solution was cooled and filtered to obtain a crude fluorenone. The content of crude fluorenone is 93%. We can recover 94% of the solvent and part of the crude fluorenone through distillation of the filtrate. The crude fluorenone is purified by directional crystallization to obtain yellow flaky fluorenone that have a purity of 99.8% or more.
9-Fluorenone is used in the preparation of antimalarial drugs. It is a fluorene derivative. Further, it is used in functional polymer and in dyes.
9-Fluorenone has been extensively used as a precursor to synthesize a variety of organic electronic materials. Some of the general examples are:
Synthesis of host for the blue and green phosphorescent organic light emitting diodes (PHOLEDs).
Synthesis of fluorene-based molecular motors.
Synthesis of open-shell Chichibabin′s hydrocarbons as potential organic spintronic materials.
It also acts as a sensitizer in the formation of picene via photosensitization of 1,2-di(1-naphthyl)eth ane.
