Product Description
Iso-pentane(2-Methylbutane)  Applications.
Isopentanes are some of the primary blowing agents used in the production of polystyrene foam and other foams. Usually, a mixture of n-, i-, and increasingly cyclopentane is used for this purpose. Because of its low boiling point, low cost, and relative safety, pentane is used as a working medium in geothermal power stations. It is added into some refrigerant blends as well.
Isopentanes are relatively inexpensive and are the most volatile alkanes that are liquid at room temperature, so they are often used in the laboratory as solvents that can be conveniently evaporated. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers. They are also often used in liquid chromatography.  Isopentane is also used in a closed loop in geothermal power production to drive turbines. Isopentane is used, in conjunction with dry ice or liquid nitrogen, to freeze tissues for cryosectioning in histology.

n-Pentane can be used to prepare isopentane and can also be used as extractant. Foaming agent of polystyrene, lubricant of liquid air. It is used for low temperature thermometers, making ice, anesthetics and synthesizing amyl alcohol. Isopentane is a mixture to improve the octane number of “lead-free” gasoline. It is also the raw material for isoprene production. Isopentene and isoprene can be prepared by dehydrogenation, and isoamyl alcohol can be obtained by chlorination and hydrolysis. When the content of n-Pentane in the product is more than 95% (WT), it can be used as the desorption agent of molecular sieve dewaxing process. The product can meet the requirements of different foaming degrees after blending with different proportions of isopentane. It can be used as an efficient foaming agent for expandable polystyrene.

Overall, in recent years, pentane demand shows a fluctuating growth state, with a slow growth rate. In 2021, the demand of China’s pentane industry is 363,000 tons, and the market scale reaches 1.96 billion yuan, of which the scale of Isopentane is the largest, accounting for 46%; n-Pentane is the second, accounting for 40%; Cyclopentane and other products account for 14%.

There are three isomers of pentane, namely n-pentane, isopentane and neopentane. The physical and chemical properties of the three substances are different, so they can be separated and purified by physical methods.

At present, the annual consumption of pentane in China is nearly 66 KT, of which the consumption of EPS pentane foaming agent is about 30 kt / A, accounting for 45% of the total consumption; the consumption of pentane for polyurethane is 33 kt / A, accounting for 50% of the total consumption; the consumption of pentane carrier solvent of linear low density polyethylene is 3 kt / A, accounting for 5% of the total consumption.

The market size of cyclopentane is estimated to be $242.4 million in 2018 and is expected to reach $335.7 million by 2023, with a compound annual growth rate of 6.7%. According to the in-depth study report on the global and Chinese Cyclopentane industry in 2018-2023 issued by New World industry research, the market growth can be attributed to the increased use of cyclopentane in residential and commercial refrigerator applications.

Isopentane is a mixture to improve the octane number of “lead-free” gasoline. It is also the raw material for isoprene production. Isopentene and isoprene can be prepared by dehydrogenation, and isoamyl alcohol can be obtained by chlorination and hydrolysis.

Full automatic loading, metering and mixing system，full automatic loading for pentanes, hexanes and heptanes.

These solvents like pentanes, hexanes, heptanes and octanes need to be managed carefully to minimize risks of a fire or explosion, whether use occurs in the home or in an industrial setting—particularly during loading and unloading, storing, and when using in bulk.

Our successful risk management systems

Solvent storage, handling and processing conditions must be carefully controlled to prevent inci-dents. The control process is known as managing risk.
