    Fluorene (CAS NO 86-73-7)
    Potassium melting method
    Raw materials for the 290 ~ 310 ℃ fluorene fraction. The fluorene fraction was fractionated and cut into fluorene narrow fractions of 292 to 302 ° C. The fluorene narrow cut plus potassium hydroxide at 280 ~ 300 ℃ under the melting, hydrolysis, remove impurities to obtain crude fluorene. Recapitalization of crude fluorene, resulting 292 ~ 298 ° C fractions obtained by recrystallization of industrial fluorene. Fine fluorene from industrial fluorene, in addition to using xylene – water mi.
    Usage:
    It can be used in the manufacture of pharmaceuticals, synthetic resins, dyes and various additives as well as in the manufacture of detergents, wetting agents, liquid glitters, pesticides, photographic materials and liquid crystal compounds.
