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 ...
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 ...
[3] [7] Commercial or laboratory-grade xylene produced usually contains about 40–65% of m-xylene and up to 20% each of o-xylene, p-xylene and ethylbenzene. [8] [9] [10] The ratio of isomers can be shifted to favor the highly valued p-xylene via the patented UOP-Isomar process [11] or by transalkylation of xylene with itself or trimethylbenzene.
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.
2-Ethylanthraquinone is prepared from the reaction of phthalic anhydride and ethylbenzene: C 6 H 4 (CO) 2 O + C 6 H 5 Et → C 6 H 4 (CO) 2 C 6 H 3 Et + H 2 O. Both phthalic anhydride and ethylbenzene are readily available, being otherwise used in the large-scale production of plastics.
Petroleum contains about one weight percent xylenes. Most o-xylene is produced by cracking petroleum, which affords a distribution of aromatic compounds, including xylene isomers.
Toluene (or methylbenzene) is a common chemical found in chemistry laboratories. An alkylbenzene is a chemical compound that contains a monocyclic aromatic ring attaching to one or more saturated hydrocarbon chains. [1]
