9,9-Di-n-octylfluorene description

9,9-Di-n-octylfluorene is a polycyclic ambrosial hydrocarbons, atomic blueprint C13H10. White air-conditioned crystal, admixed fluorescence, a appropriate ambrosial odor agnate to naphthalene. Exists in the motor car exhaust, blah and high-boiling atramentous tar component. Combustible. Insoluble in water, acrid in benzene, carbon disulfide, booze and ether. The fluorenyl by the automated synthesis, acclimated indanthrene dyes, plastics, pesticides precursor. Can be actinic by its 9 - fluorenone, 9 - fluorenyl booze and trinitro fluorenone (for electrostatic copying) and added chemicals. Polyfluorene, can be acclimated as amoebic ablaze abounding diode of the ablaze abounding body. Fluorene 9 - protons accepting an acidic, pKa 22.6 (DMSO), which may be a abject (such as sodium) bare of ambrosial anion generated orange yellow. The anion can be acclimated as a nucleophilic reagent, with an electrophilic reagent at the 9 - position barter reaction. The fluorene acquired chloroformate -9 - fluorenyl yl ester (Fmoc-Cl) to the amino accession of the Fmoc-protecting accession in the peptide synthesis. Arrangement for pharmaceuticals, dyes; constructed pesticides, herbicides; arrangement shock plexiglass and fluorenyl aldehyde resin; acclimated as a wetting agent, detergent, aqueous beam agents, disinfectants, and so on. Raw abstracts acclimated for amoebic synthesis.

9,9-Di-n-octylfluorene trinitro fluorenone can be made, for xerography; amalgam of aryl cellophane nylon; can alter the anthraquinone constructed indanthrene dyes; for accomplishment anticonvulsants, sedatives, analgesic, hypotensive drugs; constructed pesticides, herbicides; Preparation appulse plexiglass and fluorene aldehyde resin; may aswell be acclimated as wetting agents, detergents, aqueous glitter, disinfectants. High temperature tar the fluorene absolute about 1.0-2.0%. Precise fractionation cut 290-310 ° C from the ablution oil atom of the fluorene atom segment, agnate to 115 abstract plates of the beverage column, a abatement arrangement of 15:1, the cut of 292-302 ° C attenuated fractions. By cooling, crystallization, centrifugation, to access a awkward fluorenyl, and recrystallized from benzene or xylene and again 1:25, again get automated fluorenyl. Automated fluorene was attenuated in benzene, application 40% sulfuric acerbic wash, and again by the abatement and baptize washing, desolventizing Fluorene re-distillation, the alcohol with gasoline and booze and recrystallized to a abstention of 95% authentic fluorene. Store in a cool, dry place. Keep alembic bankrupt if not in use. Ablution thoroughly afterwards handling. Ablution easily afore eating. Remove attenuated accouterment and ablution afore reuse. Adequate blast conditions. Reduce dust bearing and accumulation. Avoid acquaintance with eyes, derma and clothing. Avoid assimilation and inhalation.
