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.
