Descripción

Descripción general

Heptane (n-Heptane) is a linear hydrocarbon. 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.

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 may be used in the following studies:

• To compose the water/sodium bis(2-ethylhexyl) sulfosuccinate (AOT)/n-heptane microemulsions, employed for the synthesis of ZnS nanoparticles.
• As a solvent for various solid n-paraffins.
• Sterol quantification method (SQM) for the determination of total intracellular ergosterol in Aspergillus fumigatus extracts.
