N-Heptane

CAS : 142-82-5

HS Code : 290110000

Packing : 137kg Per Drum or 15 Ton Per ISO Tank

Application

N-heptane is an organic compound with a chemical formula of C7H16. It is a colorless, transparent and volatile liquid, insoluble in water, soluble in ethanol and carbon tetrachloride, and miscible in ether, chloroform, acetone, and benzene. It is mainly used as Standards and solvents for determination of octane number can also be used in the preparation of organic synthesis and experimental reagents.

Usage

Heptane (and its many isomers) is widely used in laboratories as a non-polar solvent. As a liquid, it is ideal for transport and storage. In the grease spot test, heptane is used to dissolve an oil spot to show the previous presence of organic compounds on a stained paper. This is done by shaking the stained paper in a heptane solution for about half a minute.

Aqueous bromine may be distinguished from aqueous iodine by its appearance after extraction into heptane. In water, both bromine and iodine appear brown. However, iodine turns purple when dissolved in heptane, whereas the bromine solution remains brown.
