Benzene is a natural constituent of petroleum and is one of the elementary petrochemicals. Due to the cyclic continuous pi bonds between the carbon atoms, benzene is classed as an aromatic hydrocarbon. Benzene is a colorless and highly flammable liquid with a sweet smell, and is partially responsible for the aroma of gasoline.
One of the train's tank cars fell 75 feet from the bridge into the Nemadji River. The ruptured car released nearly 22,000 gallons of aromatic concentrates including liquid benzene and toluene into the river. Thirteen other derailed cars fell onto land banks. Two of these cars were carrying propane; other cars were carrying lumber. [1]
Unilever voluntarily recalled two types of Suave spray deodorant on March 30 after they were found to contain “slightly elevated levels” of a cancer-causing ingredient called benzene ...
[76] [citation needed] Combustion of benzene is the most efficient process, developed at MIT. [77] [78] These processes yield a mixture of various fullerenes and other forms of carbon. The fullerenes are then extracted from the soot using appropriate organic solvents and separated by chromatography.

Benzene was also detected in Proactiv, PanOxyl, Walgreens' acne soap bar and Walmart's Equate Beauty acne cream among others, according to Valisure. Cancer-causing chemical found in Clinique ...
The C 3-benzenes are a class of organic aromatic compounds which contain a benzene ring and three other carbon atoms. For the hydrocarbons with no further unsaturation, there are four isomers. The chemical formula for all the saturated isomers is C 9 H 12.
For example, crystallization of C 60 from benzene solution yields triclinic crystals with the formula C 60 ·4C 6 H 6. Like other solvates, this one readily releases benzene to give the usual face-centred cubic C 60. Millimeter-sized crystals of C 60 and C 70 can be grown from solution both for solvates and for pure fullerenes. [37] [38]
