Descripción

Descripción general

Heptane (n-Heptane) is an alkane hydrocarbon. It is a primary reference fuel (PRF) employed for determining the octane number of fuels in internal combustion engines.[1] Its cetane number and octane number has been reported to be 56 and 0 respectively.[1][2] Its thermal decomposition has been studied under different conditions of temperature and pressure.[3] Its oxidative dehydrogenation in the presence of magnesium oxide supported vanadium catalyst has been investigated.[4] 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).[2]

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Heptane is an environmentally preferable solvent and greener alternative to hexane and thus has been enhanced for "Safer Solvents and Auxiliaries". Click here for more information. Heptane is a linear hydrocarbon that is considered as a greener alternative to the more toxic hexane.

Aplicación

Greener alternatives to Hexane.

Heptane (n-Heptane) may be used:

• To compose a solvent mixture with diethyl ether for the purification of N-acylpyrrolidine derivatives of fatty acid methyl esters (FAMEs) by TLC.[5]
• To generate of chiral alcohols and heptanones, via whole cell double oxidation.[6]
• As a solvent in the synthesis of isopropyl acetate, via esterification of acetic acid with isopropyl alcohol catalyzed by lipase immobilized on silica.[7]
