Introduction:
Qualified fluorene products require fluorene content ≥95%. The fluorene content in the fluorene fraction cut after distillation is generally between 75% and 78%, and further separation and purification is required. At present, domestically qualified fluorene is basically prepared by solvent washing crystallization method . The method is to heat and dissolve the crude fluorene with a solvent, then lower the temperature to crystallize, separate, and dry to obtain fluorene with higher purity.
