Ethylbenzene is an organic compound with the formula C6H5CH2CH3. 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 an reaction intermediate in the production of styrene, the precursor to … See more Ethylbenzene occurs naturally in coal tar and petroleum. The dominant application of ethylbenzene is its role as an intermediate in the production of polystyrene. Catalytic dehydrogenation of … See more Ethylbenzene is produced on a large scale by combining benzene and ethene in an acid-catalyzed chemical reaction: C 6H 6 + C 2H 4 → C 6H 5CH 2CH 3 In 2012, more than 99% of ethylbenzene was produced in this way. Thus, makers of ethylbenzene are the … See more The acute toxicity of ethylbenzene is low, with an LD50 of about 4 grams per kilogram of body weight. The longer term toxicity and See more • National Pollutant Inventory - Ethybenzene Fact Sheet • NLM Hazardous Substances Databank – Ethylbenzene • EPA Chemical database See more WebJul 31, 2024 · Ethylbenzene is made commercially from benzene and ethene using phosphoric acid as the catalyst. Isopropylbenzene is made similarly from benzene and propene: Under these conditions the carbocation, which is the active substituting agent, is generated by protonation of the alkene: CH 2 = CH 2 + H + ⇌ CH 3CH + 2 CH 3CH = CH 2 + …

WebAn Aromatic Anion. The rather simple hydrocarbon 1,3-cyclopentadiene, which contains no electronegative atom to stabilize the negative charge in its anionic conjugate base, is essentially as acidic as water, where the conjugate base (hydroxide anion) is stabilized by the highly electronegative oxygen atom. WebEthylbenzene (Fig. 8 A) is a high-production aromatic hydrocarbon used principally in the production of styrene. In addition to this intended use, ethylbenzene is present at low concentrations in fuels and may be found in automobile exhaust. cuanto vale una pistola de balines
