Preparation:
-9HFluorene is an important organic chemical raw material, which is mostly extracted from the oil-washed fraction of coal tar, or from anthracene oil. The extraction and refining process of 9H-fluorene is to first batch wash the oil fraction or the anthracene oil fraction to cut the main 9H-fluorene fraction, and then refine the main 9H-fluorene fraction by cooling crystallization or solvent crystallization to obtain 9H-fluorene.
