Isomerization
A refining process that alters the fundamental arrangement of atoms in the molecule without adding or removing anything from the original material. Used to convert normal butane into Isobutane: (C4), an alkylation process feedstock, and normal pentane and hexane into isopentane: (C5) and isohexane: (C6), high-octane gasoline components.
Iso-octane
Liquid hydrocarbon used to determine the octane rating of fuels; (see also octane number)
Isopentane
A saturated branched-chain hydrocarbon: (C5H12) obtained by fractionation of natural gasoline or isomerization of normal pentane.
