What is Fluorene?

Fluorene is a polycyclic fragrant hydrocarbon with the molecular formula C13H10. White half-cracked crystals, fluorescent when impure, with a characteristic aromatic smell similar to naphthalene. Exists in high-boiling parts of car exhaust, corn silk, and coal tar. Combustible. Insoluble in water, soluble in benzene, carbon disulfide, ethanol and ether.

Fluorene Uses

Fluorene is used as a resources for organic synthesis. It can be made into trinitrofluorenone, which is made use of for electrostatic printing; it can be made use of to manufacture aryl clear nylon; it can replace anthraquinone to synthesize indanthrene color; it can be made use of to make antispasmodics, sedatives, anesthetics, and antihypertensive drugs; it can be synthesized Pesticides, herbicides; prep work of impact-resistant natural glass and fluorenal resin; likewise used as wetting agents, cleaning agents, liquid flash representatives, disinfectants, and so on.

Synthesis Method of Fluorene

1. The Fluorene content in high-temperature tar has to do with 1.0-2.0%. Cut the 290-310 ° C fluorene fraction from the clean oil portion, use a purification tower comparable to 115 theoretical plates for precision fractionation, with a reflux proportion of 15:1, and reduced the 292-302 ° C slim fraction. Via cooling, formation, and centrifugal separation, unrefined fluorene is obtained, and then recrystallized with 1:25 benzene or xylene to acquire industrial fluorene. Liquify commercial fluorene in benzene, clean with 40% sulfuric acid, and afterwards wash with reducing the effects of water and remove the service. Fluorene is re-distilled, and the extract is recrystallized with gasoline and ethanol to get pure fluorene with a pureness of 95%.

2. Created by reacting biphenyl with methylene chloride under the catalytic action of ferric chloride.

Fluorene Application

Fluorene can be obtained with industrial synthesis and is made use of as a precursor for indanthrene dyes, plastics, and pesticides. Chemicals such as 9-fluorenone, 9-fluorenemethanol and trinitrofluorenone (used for electrophotography) can be synthesized from it. Polyfluorene can be made use of as a luminophore in organic light-emitting diodes.

The 9-position proton of Fluorene is acidic, with a pKa of 22.6 (DMSO), and can be eliminated by a base (such as salt hydroxide) to generate an orange-yellow fragrant anion. This anion can act as a nucleophile and undergo a substitution reaction with an electrophile at the 9-position.

The by-product of fluorene, 9-fluorenylmethyl chloroformate (Fmoc-Cl), is made use of to offer a fluorenylmethoxycarbonyl shielding group on the amino team in peptide synthesis.
