Description and Uses
Fluorene, when pure, is found as dazzlingwhite flakes or small, crystalline plates. It is fluorescentwhen impure. Polynuclear aromatic hydrocarbons (PAHs)are compounds containing multiple benzene rings and arealso called polycyclic aromatic hydrocarbons. Molecularweight=166.23; Boiling point=293C (decomposes);Freezing/Melting point=116-117C; Flash point=151C. Hazard Identification (based on NFPA-704 MRating System): Health 1, Flammability 1, Reactivity 0.Insoluble in water.
Fluorene was used study the extraction of specific, semiconducting single-wall carbon nanotubes (SWCNTs).
