Junyuan Petroleum Group, China’s largest n-Pentane producer, has successfully achieved continuous exports for the 19th consecutive year. Recently, 260 tons of n-Pentane were shipped from Qingdao Port to Colombia, marking another solid step in the company’s steady expansion into international markets.

Over the past years, Junyuan has actively promoted the transformation and upgrading of the petrochemical industry by relying on advanced naphtha chemical technology. Its products not only hold a strong position in the domestic market but also represent a leap from “Made in China” to “Global Solutions.” Through in-depth market research and front-line engagement, Junyuan has strategically targeted regions such as Southeast Asia and South America. By collaborating with major domestic trading partners, participating in international exhibitions, and opening up trade channels along the Belt and Road, the company has significantly expanded the global reach of its n-Pentane products.

In Colombia, particularly in the port cities of Buenaventura and Cartagena, n-Pentane plays a vital role:

Blowing Agent in polyurethane (PU) and polystyrene (EPS) foams, essential for insulation in refrigerators and construction panels.

Organic Solvent in adhesives, coatings, and inks.

Electronics Cleaning Agent to remove grease and impurities in manufacturing processes.

Refrigerant Component (R601) in eco-friendly cooling systems.

Chemical Intermediate, Laboratory Applications, and Specialty Uses in fine chemicals, chromatography, and performance-enhancing materials.

With its “Terminal + Internationalization” dual-driven strategy, Junyuan has built a strong supply chain that ensures reliable delivery through ISO tanks and customized packaging solutions. The company’s efforts are also aligned with the high-level development of inland open economy pilot zones in China, while strengthening long-term cooperation with international partners.

A company spokesperson emphasized that exporting to Colombia is an important milestone in Junyuan’s international strategy. Looking ahead, Junyuan will continue to explore overseas market potential, expand export volumes, and enhance the global recognition of its brand concept — “Junyuan · More than n-Pentane.” By doing so, Junyuan Petroleum Group aims to bring more high-quality naphtha-based chemical products to the global stage and contribute to the growing recognition of Chinese manufacturing worldwide.

Summary:
n-Pentane is an important organic chemical raw material, with the chemical formula C5H12. This article will provide a scientific introduction to the properties, uses, storage methods, and applications of n-pentane in the chemical industry.

N-pentane, as a member of the alkane family, occupies an important position in the chemical industry due to its unique chemical properties and wide range of applications. Its chemical formula C5H12 indicates that n-pentane is composed of 5 carbon atoms and 12 hydrogen atoms, and belongs to a type of straight chain alkanes.

1、 The properties of n-pentane

n-Pentane is a colorless and transparent liquid with a lower boiling point (about 36 ° C) and is prone to volatilization. Its isomers include isopentane and neopentane, but the term “pentane” usually specifically refers to n-pentane. N-pentane has stable properties at room temperature, but is prone to combustion reactions at high temperatures or near ignition sources.

2、 The use of n-pentane

n-Pentane has a wide range of applications in the chemical industry. Firstly, it can be used as a low boiling solvent to dissolve some substances that are not easily soluble in water. Secondly, n-pentane is also an important foaming agent in the plastic industry, which can help plastic materials form a uniform foam structure. In addition, n-pentane can also be used as a fuel for automobiles and airplanes, and its high calorific value and good combustion performance make it an ideal energy choice.

In addition to the above applications, n-pentane also plays an important role in gas chromatography analysis and can be used as a standard substance or reference liquid. At the same time, it can also be used to manufacture chemicals such as synthetic pentanol and isopentane, providing raw material support for chemical production.

3、 Storage method of n-pentane

Due to the flammable and explosive properties of n-pentane, special attention should be paid during storage. Firstly, it should be stored in a cool and ventilated warehouse, away from flames and heat sources. The temperature of the warehouse should not exceed 29 ℃ to avoid fire or explosion accidents. Secondly, storage containers should be kept sealed to prevent the volatilization or leakage of n-pentane. In addition, n-pentane should be stored separately from oxidants and other substances to avoid chemical reactions.

Emergency leak handling equipment and appropriate containment materials should be equipped in the storage area, so that measures can be taken quickly for disposal in the event of a leak. At the same time, explosion-proof lighting and ventilation facilities should also be used to ensure the safety of the storage area.

4、 Summary

n-Pentane, as a multifunctional organic chemical raw material, plays an important role in the chemical industry. By understanding its properties, uses, and storage methods, we can better utilize n-pentane to provide support for chemical production. At the same time, we should also pay attention to its safe storage issues to ensure that no safety accidents occur during use.
