As benzene is ubiquitous in gasoline and hydrocarbon fuels that are in use everywhere, human exposure to benzene is a global health problem. Benzene targets the liver, kidney, lung, heart and brain and can cause DNA strand breaks and chromosomal damage, hence is teratogenic and mutagenic. Benzene causes cancer in animals including humans.
In the petroleum refining and petrochemical industries, the initialism BTX refers to mixtures of benzene, toluene, and the three xylene isomers, all of which are aromatic hydrocarbons. The xylene isomers are distinguished by the designations ortho – (or o –), meta – (or m –), and para – (or p –) as indicated in the adjacent diagram.
*** Benzene is a carcinogen (cancer-causing agent). *** Very flammable. The pure material, and any solutions containing it, constitute a fire risk. Safe handling: Benzene should NOT be used at all unless no safer alternatives are available. If benzene must be used in an experiment, it should be handled at all stages in a fume cupboard.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12-C 15, C 12-C 13 and C 10-C 13, for detergent use. [1] The C n H 2n+1 chain is unbranched. They are mainly produced as intermediate in the production of surfactants, for use in detergent. Since the 1960s, LABs have emerged as the dominant precursor of ...
Two different types of Suave aerosol deodorants were voluntary recalled for containing benzene, a human carcinogen. Here's what you need to know. What is the carcinogen benzene?
Flow rates must be controlled, and all the equipment used must be electrically interconnected and well grounded. Commercial aviation uses a similar mixture under the name Jet-B, though without the additional corrosion inhibitors and icing inhibitors included in JP-4. [4]
The Penex process is a continuous catalytic process used in the refining of crude oil. It isomerizes light naphtha (C 5 /C 6) into higher-octane, branched C 5 /C 6 molecules. It also reduces the concentration of benzene in the gasoline pool. [1] It was first used commercially in 1958. [2]
