Fluorene Chemical Properties,Uses,Production
Chemical Properties
Fluorene, when pure, is found as dazzling white flakes or small, crystalline plates. It is fluorescent when impure. Polycyclic aromatic hydrocarbons (PAHs) are compounds containing multiple benzene rings and are also called polynuclear aromatic hydrocarbons.
Physical properties
Small white leaflets or crystalline flakes from ethanol. Fluorescent when impure.
Uses
Fluorene was used study the extraction of specific, semiconducting single-wall carbon nanotubes (SWCNTs).
Definition
ChEBI: An ortho-fused tricyclic hydrocarbon that is a major component of fossil fuels and their derivatives
General Description
White leaflets. Sublimes easily under a vacuum. Fluorescent when impure.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as Fluorene, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
Hazard
Questionable carcinogen.
Health Hazard
ACUTE/CHRONIC HAZARDS: Fire hazards: Slight, when exposed to heat or flame.
Potential Exposure
Fluorene is used in resins, dyes, and is a chemical intermediate.
Shipping
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz ardous material, Technical Name Required.
Purification Methods
Purify fluorene by chromatography of CCl4 or pet ether (b 40-60o) solution on alumina, with *benzene as eluent. Crystallise it from 95% EtOH, 90% acetic acid and again from EtOH. Crystallisation using glacial acetic acid retains an impurity which is removed by partial mercuration and precipitation with LiBr [Brown et al. J Am Chem Soc 84 1229 1962]. It has also been crystallised from hexane, or *benzene/EtOH, distilled under vacuum and purified by zone refining. [Gorman et al. J Am Chem Soc 107 4404 1985, Beilstein 5 IV 2142.]
Incompatibilities
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explo sions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Compound can react exo thermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel Crafts reaction.
Waste Disposal
Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately when there is a release of this designated hazardous substance, in an amount equal to or greater than its RQ listed above. The toll free number of the NRC is (800) 424-8802; In the Washington D.C. metro politan area call (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (Section IV. D.3.b).
