Chemically and physically, n-Pentane behaves very similarly to Isopentane. Its boiling point is higher (35 °C). Pentane, n-, CP (Chemically pure)  occurs in volatile petroleum fractions(gasoline) and as a constituent of petroleum ether.

In addition, Pentane is a straight chain alkane consisting of 5 carbon atoms. It has a role as a non-polar solvent and a refrigerant. It is a volatile organic compound and an alkane. n-Pentane is a pentane isomer with straight chain normal structure. It is a clear, colorless solution with a mild and gasoline-like odor. n-Pentane is a low-boiling solvent, which greatly increases the safety demands to work with it.

Product Applications

In addition to the above mentioned, Normal Pentane (Pentane) is used principally as a blowing agent in foam production, as a propellant in aerosols and as reaction media for polymerisation processes. It is also used in the laboratory as solvents that can be conveniently and rapidly evaporated.

Highest quality 99+% n-Pentane. Pentanes are relatively inexpensive and are the most volatile liquid alkanes at room temperature, so they are often used in the laboratory as solvents that can be conveniently and rapidly evaporated.

However, because of their nonpolarity and lack of functionality, they dissolve only nonpolar and alkyl-rich compounds. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers. They are often used in liquid chromatography.

Emergency Management
1、 Leakage emergency treatment
Quickly evacuate the personnel in the leakage contaminated area to the safe area, isolate them and strictly restrict their access. Cut off the fire source. It is recommended that emergency treatment personnel wear self-contained positive pressure respirator and fire protective clothing. Cut off the source of leakage as much as possible. Prevent entry into restricted spaces such as sewers and flood drainage ditches. Small leakage: absorb with activated carbon or other inert materials. It can also be washed with emulsion made of non combustible dispersant and diluted with lotion to put into the waste water system. Massive leakage: build a dike or dig a pit to receive; Cover with foam to reduce steam damage. Transfer to tank car or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.
2、 Protective measures
Respiratory protection: when the concentration in the air exceeds the standard, wear self-priming filter gas mask (half mask).
Eye protection: generally, no special protection is required. Chemical safety glasses can be worn when exposed to high concentration.
Body protection: wear anti-static work clothes.
Hand protection: wear benzene and oil resistant gloves.
Others: smoking is strictly prohibited at the work site. Avoid long-term repeated contact.
3、 First aid measures
Skin contact: take off the contaminated clothes and wash the skin thoroughly with soapy water and clear water.
Eye contact: lift the eyelids and rinse with flowing water or normal saline. See a doctor.
Inhalation: quickly leave the site to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. See a doctor.
Ingestion: drink enough warm water, induce vomiting and seek medical advice.
Fire extinguishing method: spray water to cool the container, and move the container from the fire site to an open place if possible. If the container in the fire site has changed color or generated sound from the safety pressure relief device, it must be evacuated immediately.
Fire extinguishing agents: foam, dry powder, carbon dioxide and sand. Extinguishing with water is ineffective.
