Factors affecting the supply of fluorene CAS 86-73-7

Fluorene exists in the high boiling point components of coal tar, and the content in high temperature coal tar is about 1%-2%. The preparation of fluorene is based on the residual oil remaining from the coking washing oil processing as the raw material, rectifying to obtain a fluorene-rich fraction, and obtaining the finished product through cooling, crystallization, separation, extraction and other processes. Therefore, the production of fluorene is closely related to the production of coal tar, and the production of high-temperature coal tar directly affects the supply of fluorene.
