Introduction:
Under strong alkaline conditions, 9-fluorene methanol is prone to single-molecule elimination reaction, losing one molecule of water, and producing 9-methylene ylfluorene (dibenzofulvene). 9-Methylenefluorene easily polymerizes to form an insoluble, resin-like polymer. The polymer encapsulates 9-fluorene methanol, which is not easy to separate from 9-fluorene methanol. In addition, 9-fluorene methanol can also undergo a bimolecular elimination reaction under alkaline conditions, losing one molecule of water to produce 9-(fluorenyl-9-methylene>-9-hydroxymethyl fluorene. In 9-fluorene methanol During the synthesis process, attention should be paid to control the reaction conditions to avoid the formation of the above two by-products.
