  2. Conversion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Conversion_(chemistry)

    Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...

  3. Alkane metathesis - Wikipedia

    en.wikipedia.org/wiki/Alkane_metathesis

    These systems catalyze the conversion of ethane to give methane, propane and traces of butane. [1] Cross metathesis can also take place, for example methane and propane can react to give two molecules of ethane. Ethane reacts with toluene to give ethylbenzene and xylene. The reaction involves metallocyclobutane intermediates just as in olefin ...

  4. Ethane - Wikipedia

    en.wikipedia.org/wiki/Ethane

    Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː θ eɪ n / EE-thayn) is a naturally occurring organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by ...

  5. Diethylbenzenes - Wikipedia

    en.wikipedia.org/wiki/Diethylbenzenes

    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 ...

  6. Ethylene - Wikipedia

    en.wikipedia.org/wiki/Ethylene

    Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in 2016 [8]) exceeds that of any other organic compound. [ 9 ] [ 10 ] Much of this production goes toward creating polythene , which is a widely used plastic containing polymer chains of ethylene units in various chain lengths.

  7. Ethylbenzene - Wikipedia

    en.wikipedia.org/wiki/Ethylbenzene

    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.

  8. Benzene - Wikipedia

    en.wikipedia.org/wiki/Benzene

    Benzene is an organic chemical compound with the molecular formula C 6 H 6. The benzene molecule is composed of six carbon atoms joined in a planar hexagonal ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.

  9. Catalytic reforming - Wikipedia

    en.wikipedia.org/wiki/Catalytic_reforming

    A side reaction is hydrogenolysis, which produces light hydrocarbons of lower value, such as methane, ethane, propane and butanes. Continuous Catalytic reforming (CCR) unit In addition to a gasoline blending stock, reformate is the main source of aromatic bulk chemicals such as benzene , toluene , xylene and ethylbenzene , which have diverse ...
