  2. Butane - Wikipedia

    en.wikipedia.org/wiki/Butane

    The operating pressure for butane is lower than operating pressures for halomethanes such as Freon-12 (R-12). Hence, R-12 systems, such as those in automotive air conditioning systems, when converted to pure butane, will function poorly. Instead, a mixture of isobutane and propane is used to give cooling system performance comparable to R-12. [28]

  3. Butyraldehyde - Wikipedia

    en.wikipedia.org/wiki/Butyraldehyde

    Butyraldehyde undergoes reactions typical of alkyl aldehydes, and these define many of the uses of this compound.Important reactions include hydrogenation to the alcohol, oxidation to the acid, and base-catalyzed condensation.

  4. Natural-gas condensate - Wikipedia

    en.wikipedia.org/wiki/Natural-gas_condensate

    In general, gas condensate has a specific gravity ranging from 0.5 to 0.8, and is composed of hydrocarbons such as propane, butane, pentane, and hexane. Natural gas compounds with more than two carbon atoms exist as liquids at ambient temperatures and pressures. [4] Propane, butane, and isobutane are

  5. Butyl group - Wikipedia

    en.wikipedia.org/wiki/Butyl_group

    In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:

  7. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    This is helpful when converting from condensed formula to another form of structural formula such as skeletal formula or Lewis structures. There are different ways to show the various functional groups in the condensed formulas such as aldehyde as CHO, carboxylic acids as CO 2 H or COOH, esters as CO 2 R or COOR. However, the use of condensed ...
