Rearrangement of the atoms within hydrocarbon molecules. Isomerization processes of practical significance in petroleum chemistry are (1) migration of alkyl groups, (2) shift of a single-carbon bond in naphthenes, and (3) double-bond shift in olefins. See also Aromatization; Cracking; Molecular isomerism.
A process in which one isomer is formed from another.

| isometric, isomorph, isomorphic |
The process whereby any isomer is converted into another isomer, usually requiring special conditions of temperature, pressure, or catalysts.
