Descrição

General description

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.
