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 material.
Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2. Its structure consists of a vinyl group as substituent on benzene. Styrene is a colorless, oily liquid, although aged samples can appear yellowish. The compound evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor.
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.
Lu said sourcing ethylbenzene from plastic waste solves two problems. “One, we solve the waste plastic issue, because p ... Once the polystyrene is depolymerized to become styrene, Lu said it ...
Ethylbenzene (not a true xylene but present in mixtures called "mixed xylenes") Styrene; Phenylacetylene; 1,2-Dimethylbenzene. 1,3-Dimethylbenzene. 1,4-Dimethylbenzene.
Benzene reacted with ethylene to form the liquid hydrocarbon ethylbenzene. Ethylbenzene could be hydrogenated to form the flammable liquid monomer styrene. Styrene could be used to make the hydrocarbon polymer polystyrene. [20] The Dow Physics Laboratory began working with styrene in 1931. [20]: 92 Styrene was difficult to process. Reactions ...
ABS is derived from acrylonitrile, butadiene, and styrene. Acrylonitrile is a synthetic monomer produced from propylene and ammonia; butadiene is a petroleum hydrocarbon obtained from the C4 fraction of steam cracking; styrene monomer is made by dehydrogenation of ethylbenzene, a hydrocarbon obtained in the reaction of ethylene and benzene.
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 ...
