Fluorene

It forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene.For commercial purposes it is obtained from coal tar,[3] where it was discovered and named by Marcellin Berthelot in 1867.[8] Fluorene can be found after the incomplete combustion of plastics such as PS, PE and PVC.[10]) Deprotonation gives the stable fluorenyl anion, nominally C13H9−, which is aromatic and has an intense orange colour.The purification of fluorene exploits its acidity and the low solubility of its sodium derivative in hydrocarbon solvents.
NFPA 704 four-colored diamond Health 1: Exposure would cause irritation but only minor residual injury. E.g. turpentine Flammability 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oil Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
