Introduction:
High-temperature coal tar contains about 1% to 2% 9h-fluorene, which is mainly distributed in the wash oil fraction and general anthracene oil fraction. The content in the wash oil fraction is 6%-9%, and the content in the general anthracene oil fraction is about 2.4%. The separation and refining of 9h-fluorene can be used as raw materials for washing oil distillation residual oil, heavy washing oil or low naphthalene washing oil. First, the raw material is rectified to cut the narrow 9h-fluorene-rich fraction, and then purified by cooling crystallization method or solvent crystallization method to obtain 9h-fluorene.
