2,2,4-Trimethylpentane (TMP, isooctane), a volatile organic solvent
[1] is used to improve the octane rating of combustion fuels.
[2] TMP is a primary reference fuel with an arbitrary octane number of 100 as it burns smoothly without resulting in any knocking.
[3] It also a component of gasoline.
[1] The physical characteristics of the binary mixtures of
n-heptane and 2,2,4-trimethylpentane has been studied that helps in understanding the combustion process of mixtures of primary reference fuels.
