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.

N-PENTANE INDUSTRY DEVELOPMENTS
Junyuan Petroleum Group manufactures a wide range of solvents and fluids for industrial use. n-Pentane is one of the solvent available in different composition and is widely used in industrial sector.

There are two methods to produce isoprene by dehydrogenation: isopentane dehydrogenation and isopentene catalytic dehydrogenation. 1、 Isopentane dehydrogenation method The two-step catalytic dehydrogenation method of isopentane was first developed by the former Soviet Union and was industrialized in 1968. The raw material isopentene used in the isopentene dehydrogenation process is from catalytic cracking or straight-run gasoline. The process is mainly divided into three steps: first, the isopentane is dehydrogenated to isopentene, and a fluidized bed reactor similar to catalytic cracking is used, and the catalyst is spherical chromium-alumina oxide; Then isoprene is obtained by catalytic dehydrogenation of isoprene, and the plate-shaped calcium-nickel-phosphoric acid catalyst and adiabatic fixed-bed reactor are used; Finally, the dehydrogenation product is extracted and distilled with dimethylformamide or acetonitrile in two extractive distillation columns to obtain crude isoprene, and then the high-purity product is obtained after alkali treatment, hydrogenation and acetylene removal. In order to obtain the conversion rate beneficial to industrial production, the reaction must be carried out at high temperature (above 500~600 ℃), resulting in the increase of side reactions such as pyrolysis and isomerization. Therefore, although the raw materials of this method are cheap and easy to obtain, the cost and consumption quota are high, the process for preparing high-purity products is complex, and the development prospect is lacking. At present, only some enterprises in Russia and Eastern Europe apply this method to produce isoprene, with a total production capacity of about 300000 t/a. 2、 There are three isomers of isopentene by catalytic dehydrogenation of isopentene: 2-methyl-1-butene, 2-methyl-2-butene and 3-methyl-1-butene, of which 2-methyl-2-butene is the most suitable precursor for the synthesis of isoprene. In 1961, Shell Company of the United States built a 18000 t/a isoprene production unit using isoprene catalytic dehydrogenation method, and the production capacity of this method has reached 190000 t/a. The process flow is divided into three steps: extracting and separating isopentene from C5 fraction, a by-product of the catalytic cracking unit of the refinery; Isopentene was dehydrogenated at 600 ℃ in a fixed-bed adiabatic reactor using iron oxide, chromium oxide and carbonate catalysts; The dehydrogenation product is extracted, distilled and refined to obtain isoprene product with purity of 99.2%~99.7%. This method can use isopentene (10%~30%) with a wide range of mass fraction as raw material. Among the many methods for producing isoprene, extractive distillation has certain advantages in technology and economy. In economy, only alkenal method can be compared with extractive distillation, and the production cost of other methods is higher. Summary: From an economic point of view, the isoprene dehydrogenation technology developed by the former Soviet Union to produce isoprene has been declining and cannot be compared with the cracking C5 separation method. For the students participating in the chemical design competition, it is even more difficult to check the documents of the former Soviet Union decades ago. Even if they find them, they are still in Russian, and they can’t understand them. From a technical point of view, the reaction part is similar to the catalytic cracking unit, which is extremely complex, with many side reactions, more complex components and great difficulty in product separation. It is conceivable that such a huge workload and technical difficulty will defeat a large number of heroes.

Description

Cyclopentane is the lightest non-polar cycloalkane solvent used by the chemical industry. Its cyclical structure provides a higher solubility coefficient than branched or linear hydrocarbons, while its low molecular weight results in one of the lowest heat of vaporization values a among non-aromatic hydrocarbon solvents.

Features

• High solubility coefficient

• non polar

• low heat vaporization

Cyclopentane is used as green blowing agent and involved in the production of polyurethane insulating foam, which is used in refrigerators, freezers, water heaters, construction panels, insulated pipes and roofs. As a lubricant, it finds applications in computer hard drives and outer space equipment due to its low volatile nature. It is widely useful in the preparation of resin, adhesives and pharmaceutical intermediate. It is an additive in gasoline. Since it is a halogen free compound and has zero-ozone depletion potential, it replaces the conventionally used chloro fluoro carbon (CFC) in refrigeration and thermal insulation.
