n-Pentane | Isopentane | Cyclopentane

In today’s global chemical market, Pentane isomers play a vital role across industries ranging from polyurethane foam insulation to refrigeration systems and chemical extraction processes. High-quality Pentane products—particularly n-Pentane (CAS 109-66-0), Isopentane (CAS 78-78-4), and Cyclopentane (CAS 287-92-3)—are essential raw materials for manufacturers seeking efficiency, purity, and environmental compliance.

1. Overview of Pentane Isomers

Pentane is a family of hydrocarbons (C₅H₁₂) consisting of three structural isomers:

n-Pentane — a straight-chain hydrocarbon known for its strong solvent power and consistent evaporation rate.

Isopentane (2-Methylbutane) — a branched isomer offering a lower boiling point, ideal for refrigerant and foam-blowing applications.

Cyclopentane — a cyclic hydrocarbon with excellent insulation performance and zero ozone-depleting potential (ODP).

All three are clear, colorless liquids with low toxicity, high volatility, and compatibility with a wide range of industrial materials.

2. Technical Comparison

Property	n-Pentane	Isopentane (2-Methylbutane)	Cyclopentane
CAS No.	109-66-0	78-78-4	287-92-3
Chemical Formula	C₅H₁₂	C₅H₁₂	C₅H₁₀
Boiling Point (°C)	36.1	27.8	49.3
Density (20°C, g/cm³)	0.626	0.620	0.746
Flash Point (°C)	-49	-51	-37
Applications	Solvent, extraction, blowing agent	Foam blowing, refrigerant blend	Insulation foaming agent

These distinct properties make each isomer suited for specific applications, ensuring performance consistency and compliance with global environmental standards.

3. Industrial Applications

Refrigeration & Insulation Foams:
Cyclopentane and Isopentane are widely used as eco-friendly blowing agents in polyurethane (PU) and polyisocyanurate (PIR) foam production. They offer high insulation efficiency with low global warming potential (GWP).

Solvent Extraction:
n-Pentane serves as a clean, fast-evaporating solvent in the pharmaceutical, adhesive, and oil extraction sectors.

Chemical Blends:
Blended Pentanes (n-/Isopentane or Cyclo/Isopentane) are tailored for optimized foam density, flow, and expansion performance.

4. Quality & Packaging

High-purity Pentane products (95%–99%) are available in ISO tanks, drums, and bulk deliveries, ensuring safe transportation and global supply reliability. Each batch is tested for purity, moisture, and color to meet international quality standards.

5. Sustainability & Global Reach

As environmental regulations tighten worldwide, the transition to non-CFC, non-HCFC blowing agents has accelerated. Cyclopentane and Isopentane are now preferred alternatives for manufacturers seeking greener, high-performance materials. With stable supply capability and flexible logistics, reliable Pentane suppliers help global partners maintain consistent production and cost efficiency.

For manufacturers and distributors seeking high-purity Pentane isomers that meet international standards, reliability and consistency are key. Whether you require n-Pentane for solvent extraction, Isopentane for refrigerant formulations, or Cyclopentane for eco-friendly foam production, sourcing from trusted global suppliers ensures performance and safety.

Prices of Blowing Agents have fallen for the first time since January

by Manufacturers, Producers, Suppliers Mar 14, 2022

14-MAR-22: the supply of Pentane foaming agent is sufficient and the demand is weak. Coupled with the increase of supply, the market of foaming agent products in the domestic market began to shift from tight supply and demand to oversupply. For the first time since January 2022, the price has fallen by – 1.09%.

Pentane is an aliphatic saturated hydrocarbon with stable chemical properties. It does not react with acids and bases at normal temperature and pressure. Pyrolysis occurs at high temperature above 600 ℃ or in the presence of appropriate catalyst to produce mixtures of propylene, butene, isobutene, butane and isopropane. Aluminum trichloride was used as catalyst for isomerization to produce 2-methylbutane. 2. Stability 3 Prohibited compounds: strong oxidant, strong acid, strong alkali, halogen 4 Polymerization hazard: no polymerization. Pentane products are widely used and can be used as foaming agents for expandable polystyrene and polyurethane foam systems. They are used in areas such as fluorine free refrigerators, freezers, cold storage and pipeline insulation.

The content of mixed pentane of Junyuan Petroleum Group is more than 99%; Distillation range: 34 ~ 39; Density: 620-630, acting on pentane foaming agent, oil blending pentane, medicine, pesticide intermediates, etc. Junyuan Petroleum Group sincerely welcomes people from all walks of life to consult, visit and negotiate business with strict quality assurance system and the most satisfactory service.

Application of Pentane Blowing Agent
Pentane is the main foaming agent used to produce polystyrene foam and other foams. Generally, mixtures of N -, I – and more and more cyclopentane are used for this purpose. Because of its low boiling point, low cost and relative safety, pentane is used as the working medium of geothermal power stations. It is also added to some refrigerant mixtures.
Pentanes are relatively cheap and are the most volatile alkanes that are liquid at room temperature, so they are usually used as solvents that can be easily evaporated in the laboratory. However, due to their nonpolarity and lack of functionality, they can only dissolve nonpolar and alkyl rich compounds. Pentane is miscible with most common nonpolar solvents, such as chlorocarbons, aromatics and ethers. They are also often used in liquid chromatography.
