Anthracene is used in the production of the red dye alizarin and other dyes.

Anthracene is colorless but exhibits a blue ( 400-500 nm peak ) fluorescence under ultraviolet light.

Anthracene is converted mainly to anthroquinone, a precursor to dyes.

Anthracene is an organic semiconductor.

Anthracene, as many other PAHs, is generated during combustion processes: Exposure to humans happens mainly through tobacco smoke and ingestion of food contaminated with combustion products.

Anthracene has the highest light output of all organic scintillators and is therefore chosen as a reference: the light outputs of other scintillators are sometimes expressed as a percent of anthracene light.

Anthracene is converted to a triptycene by Diels-Alder reaction of an aryne with the central benzene ring.

Anthracene in deoxygenated dimethylformamide ( DMF ) will be reduced ( An + e < sup >-</ sup > -> An < sup >-</ sup >) at the electrode surface that is at a certain negative potential.

Anthracene may also be found with multiple hydroxyl groups, as in 9, 10-dihydroxyanthracene.

Thor Hanover ( Adios-Trustful Hanover ) is a wonderful looking prospect and another good individual, with solid, rugged conformation, good, flat bone and excellent feet.

With a large and circumspect 20th-Century technique, he wove the materials of national heroes and events, national folklore and children's fairy tales -- Slavic dances and love songs -- into a solid musical literature which served his people well, and is providing much enjoyment to the World at large.

That he mastered every aspect of his medium according to his own great talents and contemporary judgments, is a good and solid symbol of his people under the tremendous pressures of proclaiming and practising the rigors of a new culture ; ;

This result suggests a very high temperature at the solid surface of the planet, although there is the possibility that the observed radiation may be a combination of both thermal and non-thermal components and that the observed spectrum is that of a black body merely by coincidence.

The received radiation is compared with the radiation from a hypothetical black body which subtends the same solid angle as the visible disk of the planet.

A very fine, gray solid ( about 15 g ) is formed, water-washed by centrifugation, and dried at 110-degrees-C ).

A solid immunity is the one effective circumstance whereby attack by a specific agent can be neutralized.

It must be remembered, however, that there are many agents for which there is no solid immunity and a partial or low-grade immunity may be broken by an appropriate dose of agent.

That is, they used opaque color throughout, getting solid highlights with active lime white.

So far these remarks, like most criticisms of Hardy, have tacitly assumed that his poetry is all of a piece, one solid mass of verse expressing a sensibility at a single stage of development.

The Plus Two remain at a fixed position with drums and guitar but the quartet covers the stage with a batch of instruments ranging from tuba to tambourine, and the beat is solid.

Paul Paray, rounding out his current stint with the orchestra, is a solid musician, and the Philharmonic plays for him.

Kid Ory, the trombonist chicken farmer, is also one of the solid anchor points of jazz.

Scientists assume that cholesterol ( from the Greek chole, meaning bile, and sterios, meaning solid ) is somehow necessary for the formation of brain cells, since it accounts for about 2% of the brain's total solid weight.

One example is the Banach – Tarski paradox which says that it is possible to decompose (" carve up ") the 3-dimensional solid unit ball into finitely many pieces and, using only rotations and translations, reassemble the pieces into two solid balls each with the same volume as the original.

Argon is colorless, odorless, and nontoxic as a solid, liquid, and gas.

Astatine is sometimes described as being a black solid ( assuming that it follows this trend ), or as having a metallic appearance ( if it is a metalloid or a metal ).

The crystalline structure of solid astatine is unknown.

An alloy is a mixture or metallic solid solution composed of two or more elements.

It is important to realize that the word problem is in fact solvable for many groups G. For example, polycyclic groups have solvable word problems since the normal form of an arbitrary word in a polycyclic presentation is readily computable ; other algorithms for groups may, in suitable circumstances, also solve the word problem, see the Todd – Coxeter algorithm and the Knuth – Bendix completion algorithm.

In some gasifiers this process is preceded by pyrolysis, where the biomass or coal is first converted to char, releasing methane and tar rich in polycyclic aromatic hydrocarbons.

Of major concern is the fact that the polycyclic aromatic hydrocarbons found in tobacco smoke are potent inducers of CYP1A2 so that smokers may require significant modification of medication dosage.

Like many other polycyclic aromatic hydrocarbons ( PAH ), anthracene is carcinogenic as listed by OSHA.

According to a study by Slabunov ( 1999 ): " The Belomorian Province is a mobile belt that evolved in a polycyclic manner.

When this requirement is not enforced, for example in the adamantanone or other polycyclic ketones, the enolization is impossible or very slow.

Phenanthrene is a polycyclic aromatic hydrocarbon composed of three fused benzene rings.

Coronene ( also known as superbenzene ) is a polycyclic aromatic hydrocarbon ( PAH ) comprising six peri-fused benzene rings.

This model is used for describing polycyclic hydrocarbons consisting of condensed systems of benzenoid rings in which no C atom belongs to more than two rings and every C atom is on the periphery.

It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower ( negligible and non-bioavailable ) PAH ( polycyclic aromatic hydrocarbon ) content.

Benzopyrene is a polycyclic aromatic hydrocarbon found in coal tar with the formula C < sub > 20 </ sub > H < sub > 12 </ sub >.

Methylcholanthrene ( MCA ) is a highly carcinogenic polycyclic aromatic hydrocarbon produced by burning organic compounds at very high temperatures.

Pentalene is a polycyclic hydrocarbon composed of two fused cyclopentadiene rings.

* A study has shown that church air is harmful and likely to contain carcinogenic polycyclic hydrocarbons when compared to roads travelled by 45, 000 cars per day.

The border of a hive is described as polycyclic, or made up of many circles, and changes as fluid leaks out and then is absorbed.
