  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 ...

    en.wikipedia.org/wiki/Van_der_Waals_constants...

    The following table lists the Van der Waals constants (from the Van der Waals equation) for a number of common gases and volatile liquids. [ 1 ] To convert from L 2 b a r / m o l 2 {\displaystyle \mathrm {L^{2}bar/mol^{2}} } to L 2 k P a / m o l 2 {\displaystyle \mathrm {L^{2}kPa/mol^{2}} } , multiply by 100.

  4. Transalkylation - Wikipedia

    en.wikipedia.org/wiki/Transalkylation

    The reaction is used for the transfer of methyl and ethyl groups between benzene rings. This is of particular value in the petrochemical industry [1] to manufacture p-xylene, styrene, [2] and other aromatic compounds. Motivation for using transalkylation reactions is based on a difference in production and demand for benzene, toluene, and xylenes.

  5. Friedel–Crafts reaction - Wikipedia

    en.wikipedia.org/wiki/Friedel–Crafts_reaction

    This reaction is related to several classic named reactions: The acylated reaction product can be converted into the alkylated product via a Clemmensen or a Wolff-Kishner reduction. [17] The Gattermann–Koch reaction can be used to synthesize benzaldehyde from benzene. [18] The Gatterman reaction describes arene reactions with hydrocyanic acid ...

  6. 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 ...

  7. Energy profile (chemistry) - Wikipedia

    Figure 6:Reaction Coordinate Diagrams showing reactions with 0, 1 and 2 intermediates: The double-headed arrow shows the first, second and third step in each reaction coordinate diagram. In all three of these reactions the first step is the slow step because the activation energy from the reactants to the transition state is the highest.

  8. Ethanol fermentation - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fermentation

    This reaction is catalyzed by alcohol dehydrogenase (ADH1 in baker's yeast). [3] As shown by the reaction equation, glycolysis causes the reduction of two molecules of NAD + to NADH. Two ADP molecules are also converted to two ATP and two water molecules via substrate-level phosphorylation.

  9. Alcohol oxidation - Wikipedia

    en.wikipedia.org/wiki/Alcohol_oxidation

    Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
