  2. Isobutane - Wikipedia

    en.wikipedia.org/wiki/Isobutane

    Isobutane is the principal feedstock in alkylation units of refineries. Using isobutane, gasoline-grade "blendstocks" are generated with high branching for good combustion characteristics. Typical products created with isobutane are 2,4-dimethylpentane and especially 2,2,4-trimethylpentane. [7] Typical acid-catalyzed route to 2,4-dimethylpentane.

    Despite their flammability, they are increasingly used in domestic refrigerators and heat pumps. In 2010, about one-third of all household refrigerators and freezers manufactured globally used isobutane or an isobutane/propane blend, and this was expected to increase to 75% by 2020.

    en.wikipedia.org/wiki/Alkylation_unit

    The isobutane feed to an alkylation unit can be either low or high purity. Low purity makeup isobutane feedstock (typically < 70% vol isobutane) usually originates from the refinery (mainly from the reformer) and need to be processed in the deisobutanizer (DIB). High purity feedstock (> 95% vol isobutane) normally originates from an external De ...

    The "prop-" root found in "propane" and names of other compounds with three-carbon chains was derived from "propionic acid", [21] which in turn was named after the Greek words protos (meaning first) and pion (fat), as it was the "first" member of the series of fatty acids. [22]
