in high temperature tar accounted for about 1.0% ~ 2.0%. Low naphthalene washing oil or washing oil residue is used as raw material, the fraction of 289~303 ℃ is cut out by rectification, cooled and crystallized, separated and pressed to obtain pressed fluorene, and industrial Fluorene is obtained after extraction with toluene.
synthetic dyes, pharmaceuticals, pesticides, engineering plastics, impact organic glass and other raw materials. Trinitrofluorenone was synthesized for xerography, and aryl transparent nylon was synthesized. Fluorene can be used instead of anthraquinone synthesis of Yin danshilin dye; Manufacturing spasm-inhibiting drugs, sedatives, analgesics, hypotensive drugs; Synthetic insecticides, herbicides; Impact organic glass and fluorene aldehyde resin; Can also be used for wetting agent, detergent, liquid scintillators, disinfectants, etc.
