                Heptane (n-Heptane) may be used:
                • To compose the solvent mixtures for the purification of N-acylpyrrolidine derivatives of fatty acid methyl esters (FAMEs) by TLC (Thin Layer Chromatography).
                • To generate chiral alcohols and heptanones, via whole cell double oxidation.
                • As a solvent in the synthesis of isopropyl acetate, via esterification of acetic acid with isopropyl alcohol catalyzed by lipase immobilized on silica.

                General description

                Heptane (n-Heptane) is a primary reference fuel (PRF) for the rating of octane numbers of fuels in internal combustion engines. Its cetane number has been reported to be 56. Mechanism and kinetic studies of its oxidation in flow reactors, shock tubes and rapid compression machines have been proposed. Its thermal decomposition has been studied under different conditions of temperature and pressure. Its oxidative dehydrogenation in the presence of magnesium oxide supported vanadium catalyst has been investigated. Molybdenum phosphide supported on Hβ zeolite (MoP/Hβ) catalyzed hydroisomerization of n-heptane has been reported to be enhanced by doping with secondary metals (Cr, Ni or Ce).
