Pentane is an organic hydrocarbon with 5 carbon atoms. Pentane is a combination of the Alcan family. The normal Pentane isomers without a Pentane branch. Pentane is often used as a solvent that is easily evaporated. Pentane is a flammable substance.

The name of the material (Persian): Normal Pentane

The name of the material (English): n-Pentane

Brand (Persian): Pentane

Brand name: Pentane

Other names: Amyl Hydride, Skelly Solution A (Skelly solve A)

 

This Alkan is one of the components of some fuels and is also used as a solvent. Pentane properties are very similar to butane and hexane. Pentane has three normal isomers of pentane, isopentane, and neoprene. The pentane branching isomers are much more stable than the normal pentane isomer. The number of hydrogen atoms of pentane and other alkanes is twice as high as the number of carbon atoms two.

Indications:

Pentane is one of the most volatile hydrocarbons at room temperature. Pentane is often used as a solvent that is easily evaporated. Since pentane is also polarized, only non-polar materials are dissolved. Pentane is also one of the common fuel components. Pentane is used as a foaming agent in foam polystyrene production. Pentane is used in geothermal force units.
