| Application: | 2,2,4-Trimethylpentane (TMP, isooctane) may be used in the following studies: • Synthesis of polyethyleneimine /silica hybrid nanoparticles. • Amino acid quantification process. • To dissolve di(2-ethylhexyl) phosphoric acid(DEHPA) to form a solution that is used in the extraction and back extraction of methylene blue. |
| General description: | 2,2,4-Trimethylpentane (TMP, isooctane), a volatile organic solvent is used to improve the octane rating of combustion fuels. TMP is a primary reference fuel with an arbitrary octane number of 100 as it burns smoothly without resulting in any knocking. It also a component of gasoline. 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. |
