APPLICATION 

·       Heptane is best recognized as the standard zero-point for the octane rating scale, which is seen on nearly every gasoline pump worldwide.

·       The hydro isomerization of n-heptane to form disbranched and tribranched products useful for producing high octane gasoline. It is used in paints and coatings, GC analysis, HPLC, spectrophotometry and environmental testing.

·       The vulcanization of rubber utilizes heptane as a compounder. In the commercial manufacture of rubber cement, vulcanized rubber is placed in a solvent of 70-90% heptane. Different grades of rubber cement are created depending on a higher or lower percentage of heptane within the solvent.
