Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3. It is a highly flammable, colorless liquid with an odor similar to that of gasoline . This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene , the precursor to polystyrene , a common plastic ...
If ethylbenzene is included, the mixture is sometimes referred to as BTEX. The BTX aromatics are very important petrochemical materials. Global consumption of benzene, estimated at more than 40,000,000 tons in 2010, showed an unprecedented growth of more than 3,000,000 tons from the level seen in 2009.
In this process, ethylbenzene is treated with oxygen to form the ethylbenzene hydroperoxide. This hydroperoxide is then used to oxidize propylene to propylene oxide, which is also recovered as a co-product. The remaining 1-phenylethanol is dehydrated to give styrene:
It is used primarily as a precursor to the manufacture of chemicals with more complex structures, such as ethylbenzene and cumene, of which billions of kilograms are produced annually. Although benzene is a major industrial chemical , it finds limited use in consumer items because of its toxicity.
Xylene is used in the laboratory to make baths with dry ice to cool reaction vessels, [17] and as a solvent to remove synthetic immersion oil from the microscope objective in light microscopy. [18] In histology, xylene is the most widely used clearing agent. [19] Xylene is used to remove paraffin from dried microscope slides prior to staining.
Diethylbenzenes arise as side-products of the alkylation of benzene with ethylene, which can be described as two steps. The first step is the industrial route to ethylbenzene, which is produced on a large scale as a precursor to styrene. C 6 H 6 + C 2 H 4 → C 6 H 5 C 2 H 5. The diethylbenzene is an inadvertent side product. C 6 H 5 C 2 H 5 ...
The dye is also commonly used in drugs and dietary supplements to color pills. If you're unsure, it's best to check the product's ingredient label before purchasing. Keep in mind that Red Dye No ...
The C 2 benzenes are a class of organic aromatic compounds which contain a benzene ring and two other carbon atoms. For the hydrocarbons with no further unsaturation, there are four isomers.
