n-Pentane, Isopentane and Cyclopentane are all saturated hydrocarbons that have five carbon atoms. They have different molecular structures and physical properties, which make them suitable for different uses. Some of the common applications for these Pentane isomers are:

• Blowing agents for insulation materials: Pentanes are the foaming agent of choice for producing Polyurethane (PU) and Polystyrene (PS) insulation boards. They have a high performance and sustainability, as they do not deplete the ozone layer or contribute to global warming. Cyclopentane has the best insulating effect, while n-Pentane and Isopentane have more stable and finer foam cells².
• Refrigerants: n-Pentane can be used as a refrigerant in air conditioning or refrigeration systems, as an alternative to ammonia or fluorinated hydrocarbons. It has a low boiling point and a high latent heat of vaporization, which means it can absorb a lot of heat when it changes from liquid to gas¹.
• Non-polar solvents: Pentanes are almost insoluble in water, but show very good solubility or unlimited miscibility with many organic solvents such as paraffins, ethers, esters, aromatics or chlorinated hydrocarbons. They are also very volatile, which means they evaporate quickly and leave no residue. Therefore, they are suitable for cleaning in the aerospace, automobile, electronic, and defense manufacturing industries¹⁵.
• Process media for polyethylene and polypropylene: Pentanes can be used as process media for the production of polyethylene (PE, LLDPE) and polypropylene (PP), which are widely used plastics. Pentanes help to control the molecular weight, branching and crystallinity of the polymers, which affect their mechanical and thermal properties¹.

These are some of the main applications for n-Pentane, Isopentane and Cyclopentane. I hope this overview is helpful for you.

Choosing between n-Pentane, Isopentane and Cyclopenane depends on the intended use. Here are some general differences between them:

• Pentane is a colorless, volatile liquid, mainly used for chemical experiments, solvent and solvent mixture preparation, and also an important raw material in the petroleum industry.
• When buying pentane, you should pay attention to the following aspects:
  • Purity: The higher the purity of pentane, the better its performance and quality, but the higher the price. According to different uses, you can choose different purity grades, such as AR, CP, GCS, GR, HPLC, agricultural residue grade, etc.
  • Packaging: Pentane is a flammable liquid and should be packed and stored in suitable sealed containers to prevent leakage and fire. Generally speaking, the packaging specifications of pentane are 200L steel drums and ISO tank containers.
  • Price: The price of pentane is affected by many factors such as market supply and demand, raw material cost, transportation cost, etc., generally ranging from hundreds of USD to thousands of USD. When buying, you should compare the quotations of different manufacturers and channels, and choose products with high cost performance.
  • Manufacturer: There are many manufacturers of pentane, and there are great differences in production scale, technology level, product quality, etc. You should fully understand the qualifications, reputation, after-sales service, etc. of the manufacturers when buying. You can choose regular, professional and reliable manufacturers through the Internet, industry associations, peer recommendations, etc.

The Oigin of Cyclopentane
A colorless, water-insoluble liquid, C5H10, obtained from petroleum and used chiefly as a solvent. Cyclopentane is a flammable liquid and its vapors can be explosive. Cyclopentane has a bond angle of about 108°C. This minimal ring strain for cyclopentane makes it a more stable compound.

Cyclopentane is in the class of cycloalkanes, being alkanes that have one or more carbon rings. It is formed by cracking cyclohexane in the presence of alumina at a high temperature and pressure.

Cyclopentane is a twisted ring in the form of an “envelope” so that one of the carbon atoms is out of the plane of the ring.

Cyclopentane is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S.

Cyclopentane is formed from pentane and is an alicyclic hydrocarbon compound that falls in the category of an alkane.

Cyclopentane is treated with chlorine in the presence of light or heat to form chloro cyclopentane which then reacts with KOC(CH3)3 forming cyclopentene. Cyclopentane has a bond angle of about 108o. This minimal ring strain for cyclopentane makes it a more stable compound. Besides, this compound occurs as a colourless liquid, and it is flammable. Moreover, it has a petrol-like odour. Cyclopentane is a simple hydrocarbon. If 0.0956 g of the compound is combusted in oxygen, 0.300 g of carbon dioxide and 0.123 g of water are produced.

Cyclopentane makes important contribution to energy efficiency. Junyuan Petroleum Group is a leading manufacturer of Pentanes in China.

Top 5 Uses of Pentane

Pentane is a cost-effective liquid that has several different industrial and laboratory applications.

1. Laboratory Solvents

They are the most volatile liquid alkanes (at room temperature). Because of this, they are commonly used in laboratories as solvents. Although, due to their lack of functionality and non-polarity, they only dissolve other nonpolar and alkyl-rich compounds. Pentanes are miscible with other solvents like ethers, aromatics, and chlorocarbons.

2. Chromatography

Pentane is commonly used in chromatography – which is a laboratory technique to separate components in a mixture. The mixture is passed in a suspension or solution through a medium where the components each move at different rates.

3. Blowing Agent

Pentane is used as the primary blowing agent in the production of foams like polystyrene. A blowing agent is a substance that is capable of producing a cellular structure through a foaming process. These foams are often used as insulating material in refrigerators and heating pipes

4. Binary Fluid

Because of its low boiling point, pentane is used in geothermal power stations as a binary fluid.

5. Industrial Ingredient Uses

Due to its ready availability and low cost, pentane is also used as a solvent in many common products like pesticides. It can also be used in making other chemicals, plastics, and low-grade thermometers. Acid-catalyzed isomerization can produce isopentane, which can be used in making fuels.

The price of EPS products in the Chinese market today is CNY10,122.8/MT, down -0.29% from the previous trading day

Pentane is the most common expansion agent in EPS production. Low concentration of pentane can be trapped during production, inside the closed cells of EPS. By the end of the production cycle, EPS products may still contain 1-2% of Pentane by weight.

What is EPS foam made of?
WHAT IS EPS? Expanded Polystyrene (EPS) is a rigid, closed cell, thermoplastic foam material produced from solid beads of polystyrene, which is polymerised from styrene monomer and contains an expansion gas (pentane) dissolved within the polystyrene bead.

type of foam is EPS?
expanded polystyrene foam
The foam that you formerly knew as styrofoam is actually expanded polystyrene foam or EPS. This material is made from polystyrene, a plastic that’s often used to make clear products like food packaging or lab equipment.

What are the different types of polystyrene?

What Are The Different Types of Polystyrene? Three major types of polystyrene include polystyrene foam, regular polystyrene plastic, and polystyrene film. Amongst the different types of foam are expanded polystyrene (EPS) and extruded polystyrene (XPS).

Polyurethane foam is widely used in construction, refrigeration, piping and other fields due to its low density, good thermal insulation, low water absorption, low toxicity, and good processability. The blowing agent is an important auxiliary agent for the production of polyurethane foam plastics. Since the second-generation blowing agent HCFC-141b has an ODP value of 0.11 and a GWP value of 725, it has a great impact on the ozone layer and the greenhouse effect, so it can only be used as a transitional agent. use of sex substitutes. According to China’s polyurethane foam industry HCFC-141b phase-out plan (second phase), the polyurethane foam industry will gradually reduce HCFC-141b consumption based on the results achieved in the first phase, and will achieve industry-wide phase-out by the end of 2025. At present, the commonly used substitutes for HCFC-141b blowing agent mainly include pentane, water, hydrofluorocarbon (HFC), liquid carbon dioxide, hydrofluoroolefin (HFO) and methyl formate. Among them, pentane is widely used due to its advantages of environmental protection, low price, and easy availability. However, pentane is flammable and explosive, and is a dangerous chemical. The use of this kind of blowing agent requires safety renovation of production equipment and workshops. Although the initial investment of pentane foaming replacement technology is relatively high, in the long run, the comprehensive economic benefits are obvious, and it is an ideal substitute for HCFC-141b.
