		ANTHRACENE (from the Greek civOpa, coal), C 14 H 10, a hydrocarbon obtained from the fraction of the coal-tar distillate boiling between 270° and 400° C. This high boiling fraction is allowed to stand for some days, when it partially solidifies.
		Numerous sulphonic acids of anthracene are known, a monosulphonic acid being obtained with dilute sulphuric acid, whilst concentrated sulphuric acid produces mixtures of the anthracene disulphonic acids.
		By the action of sodium amalgam on an alcoholic solution of anthracene, an anthracene dihydride, C14H12, is obtained, whilst by the use of stronger reducing agents, such as hydriodic acid and amorphous phosphorus, hydrides of composition C14H16 and C14H24 are produced.

	Anthracene - Wikipedia, the free encyclopedia
		In chemistry, anthracene is a solid polycyclic aromatic hydrocarbon consisting of three benzene rings derived from coal-tar.
		A classis method for the preparation of anthracene in the laboratory is by cyclodehydration of o-methyl- or o-methylene-substituted diarylketones in the so-called Elbs reaction (Karl Elbs, 1858-1933).
		Anthracene is used as a scintillator for detectors of high energy photons, electrons and alpha particles.

	Process for separating alpha and internal olefins - Patent 4946560
		Anthracene is utilized in the instant process to form the adduct primarily with the alpha olefin in the feedstock.
		The process of the instant invention is basically a three step process wherein (a) anthracene is reacted with the olefin to form an adduct, (b) the adduct is separated from the reaction mixture and (c) the adduct is pyrolized to release the olefin and regenerate the anthracene.
		The solid anthracene and dodecene-anthracene adduct were pyrolyzed in a nitrogen flow-pot heated to 300.degree.-350.degree.
