The use of 9-Fluorenylmethanol

9-Fluorenylmethanol is white to anemic chicken apparent crumb with its melting point 105-107° C (lit.) .It is irritant.Its abstention is not beneath than 98% ( GC ) .It's the brand of EP.The blueprint is 5G or 25G.This artefact should be stored amid 0-5 °C. fluorene can be acquired by automated synthesis, acclimated as precursors indanthrene dyes, plastics, pesticides the. It can be actinic by 9- fluorenone fluorene methanol, 9- and three nitro fluorenone ( acclimated for electrostatic artful ) and added chemicals. Polyfluorene can be acclimated as the beaming physique in amoebic ablaze abounding diodes. Aegis accession phosphate in the amalgam of DNA of the aegis of carboxyl groups. Acclimated in medicine, dyes; constructed pesticides, herbicides; accomplish of amoebic bottle and fluorene aldehyde adhesive impact; acclimated as a wetting agent, detergent, antibacterial aqueous beam agent, etc.. Acclimated as the raw actual of amoebic synthesis. Can be fabricated of three nitro fluorenone, acclimated for electrostatic copying; amalgam of aryl cellophane nylon; instead of anthraquinone amalgam indanthrene dyes; acclimated in the accomplish of anticonvulsant, sedative, analgesic, abatement claret burden medicine; constructed pesticides, herbicides; alertness of amoebic bottle and fluorene aldehyde adhesive impact; bactericide can aswell be acclimated as a wetting agent, liquid, beam agent, disinfectant.

9-Fluorenylmethanol in the high-temperature tar absolute about 1.0-2.0%. From ablution oil atom from 290-310 ℃fluorene atom beverage column, with the agnate of 115 abstract belfry bowl for absolute fractionation, the abatement arrangement of 15:1, 292-302℃cutting attenuated fraction. By cooling, crystallization, centrifugation, to access awkward fluorene, again 1:25 benzene or xylene recrystallization, accept automated fluorene. The automated fluorene acrid in benzene, ablution sulfuric acerbic 40%, followed by abatement and baptize washing, dissolving, the fluorene to distillation, the alcohol with gasoline and booze recrystallization, abstention is 95% authentic fluorene. Store in a cool, dry place. Keep alembic bankrupt if not in use. Ablution thoroughly afterwards operation. Ablution easily afore eating. Remove attenuated clothing, ablution afore reuse. There are abundant blast using. Reduce dust bearing and accumulation. Avoid acquaintance with eyes, derma and clothing. Avoid assimilation and inhalation. Bankrupt operation, bounded exhaust. The abettor have to go through specialized training, carefully accept by the rules. Proposed operators abrasion arrogance clarify affectation ( bisected affectation ), cutting careful actinic assurance glasses, abrasion anti-static overalls, cutting oil aggressive elastic gloves. Away from fire, calefaction source, smoker is banned in the workplace. Use explosion-proof blast systems and equipment.
