Extensive Definition
2,2,4-Trimethylpentane, also known as isooctane,
is an octane isomer which defines the 100
point on the octane
rating scale. It is an important component of gasoline.
Isooctane is produced on a massive scale in the
petroleum industry,
usually as a mixture with related hydrocarbons. The alkylation process alkylates
isobutane with
isobutylene using a
strong acid catalyst. In the NExOCTANE process, isobutylene is
dimerized into isooctene and then
hydrogenated to isooctane.
