  3. Ethane - Wikipedia

    en.wikipedia.org/wiki/Ethane

    Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː-/ EE-) 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-product of petroleum ...

    The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera).

  5. Benzene - Wikipedia

    en.wikipedia.org/wiki/Benzene

    In the body, benzene is enzymatically converted to a series of oxidation products including muconic acid, phenylmercapturic acid, phenol, catechol, hydroquinone and 1,2,4-trihydroxybenzene. Most of these metabolites have some value as biomarkers of human exposure, since they accumulate in the urine in proportion to the extent and duration of ...

  6. Catalytic reforming - Wikipedia

    en.wikipedia.org/wiki/Catalytic_reforming

    Catalytic reforming is a chemical process used to convert naphthas from crude oil into liquid products called reformates, which are premium "blending stocks" for high-octane gasoline. The process converts low-octane linear hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes , which are then partially ...

  7. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    One or more of the hydrogen atoms can be replaced with other atoms, for example chlorine or another halogen: this is called a substitution reaction. An example is the conversion of methane to chloroform using a chlorination reaction. Halogenating a hydrocarbon produces something that is not a hydrocarbon. It is a very common and useful process.

  8. 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 ...

  9. 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.
