Примери за benzene

• Benzene, a substance compounded of carbon and hydrogen, obtained by destructive distillation from coal-tar and other organic bodies, used as a substitute for turpentine and for dissolving grease. 

• If you are after the greatest yield of tar products, you impoverish the gas by taking out the benzene and get a blue instead of a bright yellow flame. 

• It is very soluble in water, easily soluble in boiling alcohol, much less in cold alcohol, and insoluble in ether, chloroform and benzene. 

• Remove paint stains with benzene or turpentine, machine oil with cold water and Ivory soap, vaseline with turpentine. 

• Six atoms of carbon and six of hydrogen put together in a certain way make benzene. 

• Apart from the benzene alcohols, theaspirene was the compound with the highest concentration in the wines of all three varieties in 2003 vintage.

• This sample also contained elevated levels of benzene, ethylbenzene, toluene, and xylenes.

• Solvent removal during curing process of highly spheric and monodispersed-sized polystyrene capsules from densitymatched emulsions composed of water and benzene/1, 2-dichloroethane.

• This breakthrough came about through the availability of the benzene ring theory.

• In surface soils, the ratio of formic acid to benzene increases with decreasing precipitation, suggesting a high degree of oxidation at the driest site.

• In a classic example, they used an organic solvent called pazoxyanisole and benzene as a solute.

• For example, we are informed by the researchers that people with lung cancer tend to exhale a mixture of alkanes and benzene derivatives.

• The combined benzene solutions were washed five times with 2 ml of water.

• Thousands of people will have seen such images without ever connecting this to the chemical structure of benzene.

• Indications were also found of the anaerobic biodegradation of benzene within the aquifer.

• In a real experiment obvious candidates for such molecules are benzene, other aromatic compounds, or even nanotubes.

• Once benzene is produced, the synthesis of more complex compounds occurs via simple substitution or addition reactions.

• For example, benzene measurements were made but high cross-sensitivity to carbon monoxide meant that the results were invalid.

• Closely related to the benzene ring were its condensed forms, naphthalene and anthracene.

• The lower, middle, and upper layers were a sodium hyposulfite -glycerin solution, a water-glycerin solution, and benzene, respectively.
