Descrição

Descrição geral

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.

Aplicação

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.
