The product of Isohexane is still unfamiliar to many people. It has existed in the market for a very long time, but in the last two years, it has attracted more attention from the industry due to the deepening of industrial structure. So what is Isohexane?
Isohexane is a light component of C6, and at present, there is no manufacturer producing it alone, and most of them are produced with n-Hexane. However, many cleaning markets and even high-end precision cleaning agent markets have been occupied by Isohexane.

First of all, from the perspective of raw materials, as the cleaning agent has high requirements on the control of sulfur and chlorine content and other trace elements and harmful substances, due to the limitation of technology and equipment, the higher purity Isohexane has the better use experience, so coal naphtha is the raw material for high-purity Isohexane.
From its own properties, Isohexane is light in density, easy to volatilize and tasteless. It also performs well in aerosol preparation. However, this characteristic is also the reason why it is difficult to be a good solvent for vegetable oil extraction like n-Hexane. The distillation range of Isoexane is less than 2 degree, which therefore makes it very inconvenient for workers to operate. According to the current domestic device and equipment parameters, the oil consumption will be greatly increased. Consequently, the production cost of Isohexane will also increase greatly, and the increase of production cost will undoubtedly affect the market price of isohexane, which is difficult to reduce in the short term.
In addition to the above characteristics, the low price is also an important reason why it can replace the traditional 6# solvent oil and other products and occupy a favorable position. In the future, more manufacturers will invest in the production and R & D of Isohexane. At present, Junyuan Petroleum Group, a giant producer of Isohexane and chemical solvents, is the largest one in the Chinese market. The situation of monopolizing the Isohexane market is about to face serious challenges.

The n-hexane market rebounded slightly this week, with gains concentrated in 60% and 80% of the food additive n-hexane. The high-purity manufacturers in the western region, because of the better shipment of n-heptane, replaced part of n-hexane, so the inventory pressure of high-purity Hexane is high, and the transaction price of low-cost raw material resources is as low as 5,500 yuan / ton.
The trend of raw material price is volatile this week, and the guidance for n-Hexane is limited. However, the domestic oil spot market rose steadily, and the market continued to speculate on the dry weather, and the soybean oil short-term showed a strong pattern. At present, 80% n-Hexane is used in corn oil extraction and soybean protein production in China. Therefore, the consumption of oil and fat market increased, and 80% n-Hexane increased significantly.
n-Hexane,60% is the largest production and consumption of n-Hexane. It is widely used in the field of edible oil extraction and all rubber production fields in China, such as butyl rubber, styrene butadiene rubber, isoprene rubber and cis-1-polybutadiene rubber. However, in recent years, the marginal profit of production enterprises has narrowed, and the overall buying atmosphere of downstream is still general, but there is generally no willingness to lower at the beginning of the month, and the price is increased to offer sales.
The trend of crude oil is difficult to predict and the demand is slightly improved. Some types of n-Hexane are still facing challenges. n-Hexane may fluctuate upward.

^{Market Research Center – Junyuan Petroleum Group}
In the past two years, n-Heptane has been performing well. Although the overall market demand is not good, most of the demand for n-Heptane comes from the pharmaceutical industry, especially the API (Active Pharmaceutical Ingredients ) industry. On the contrary, with the adjustment of national policies in China, the pharmaceutical industry is developing vigorously, so the market demand of n-Heptane is commendable.
In addition, because the relative stability of H-heptane is slightly better than that of n-Hexane, many enterprises have replaced n-Hexane with n-Heptane in the past two years, which is also a fundamental reason for the rise of n-Heptane market and the decline of n-Hexane.
In 2020, the market of n-Heptane is still developing steadily, and the demand is increasing slowly. Export is the development direction of n-Heptane. In fact, the export of n-Heptane is increasing greatly in recent years. In the future, the annual demand of n-Heptane is expected to reach 50,000 tons / year.
In 2020, with the gradual shrinkage of the market of general solvent oil and aromatic solvent oil, special oils such as n-Hexane, n-Heptane, Isoalkanes, D-series solvent oils gradually stepped onto the stage of the new year. From raw materials to downstream, from technology to policy, due to the second dip in the global economy, new pattern and changes have taken place in the solvent oil market, and Sinopec’s refineries have adjusted their product structure to withdraw from the solvent oil market.
As said above, the market of n-Heptane in China is not large, which is about 30,000-40,000 tons but not more than 50,000 tons per year.
Then why is n-Heptane always mentioned in the industry? Because n-Heptane plays an irreplaceable role in the field of pharmaceutical intermediates. At least, no effective substitutes for n-Heptane have been found.
In the past, n-Heptane was mainly relied on imports, most of which were Korean SK products. Now, Korean SK also accounts for a large sales share in the domestic market. In the past two years, due to the development of coal to liquid, the bottleneck of domestic n-Heptane manufacturers like Junyuan Petroleum Group has been greatly broken through, and today’s domestic n-Heptane has a foothold in the market.
Before, the domestic production of n-Heptane was based on petroleum basis 120 solvent oil. Due to the limited raw material conditions, the content of n-Heptane produced was just close to 97%, which was difficult to reach 98%. Even if the content reached 98%, the yield of the product could not come up, resulting in increased production costs.
With the advent of normal stable light hydrocarbon in coal chemical industry, the production of n-Heptane content can reach more than 98% effortlessly. Last year, China industry only took one year to make the content of n-Heptane more than 98%, which popularized the market. This year, it will take one year to popularize the 99% content of n-Heptane. In the future, the market will be content of n-Heptane 99%, and the quality will be more and more better. The quality is getting better, the price is getting cheaper.
Coal to n-Heptane has high yield and low production cost, which is the development trend of n-Heptane in the future. In the future, the market will become more and more difficult. Therefore, we can only work hard on the product technology to make the quality standard of products reach another higher level, which is also the inevitable law of the development of things.
Last year, it is estimated that several manufacturers failed to put into production successfully for some reason, so n-Heptane is still in a tight market stage. As more and more terminal enterprises replace n-Hexane with n-Heptane, more than 97% of the n-Hexane market will gradually shrink.

Hexane has 6 carbon atoms (black) and 14 hydrogen atoms (white).

Hexane is an organic compound made of carbon and hydrogen that is most commonly isolated as a byproduct of petroleum and crude oil refinement. At room temperature it is an odorless, colorless liquid, and it has many uses in industry. It is a very popular solvent, for instance, and is often used in industrial cleaners; it is also frequently used to extract oils from vegetables, particularly soybeans. Most vehicle-grade gasoline contains it, too. Though most experts say the compound is non-toxic and presents only low risks to humans and animals, there is still a great deal of controversy in many places when it comes to how often it is included, sometimes without full disclosure, in foods and consumer products.
Molecular Breakdown
It is usually considered to be a relatively simple molecule. As the hex- prefix indicates, it has six carbon atoms, which are accompanied by 14 hydrogen atoms giving it the molecular formula C6H14. The carbons are chained in a row, one following the next. Each carbon has at least two hydrogen atoms attached to it except for the first and last carbon, which have three. Due to its exclusive carbon-hydrogen makeup and the fact that it only has single molecular bonds, it can be classified as a straight-chain alkane.
Hexane is usually a colorless liquid, best known for being a solvent.
The compound is also easily represented visually. When drawn as a Kekulé structure, it is a line of six carbons, each of which has four line-bonds. Hydrogens surround the central carbon chain so that the condensed structure is written as CH₃CH₂CH₂CH₂CH₂CH₃. It is a simple line with five segments.
Some people who are exposed to hexane experience dizziness and nausea that worsens over time.

Benefits of Hexane

• Low boiling point.
• Low surface tension.
• Low flash point.
• Low solubility.

Physical Properties

This compound is stable at room temperature, and most commonly occurs as a colorless liquid. It has a melting point of roughly -139.54°F (-95.3°C), a boiling point of 154.04°F (67.8°C), and it’s molar mass is 86.18 grams per mole (g/mol). Hexane is also a non-polar molecule, which means that it is not soluble in water.

How It’s Extracted

Hexane occurs in a couple of different places in nature, but is usually most readily available in petroleum deposits. This is often why gasoline contains it in high concentrations. When petroleum and petroleum-containing oils are mined and refined, chemists are often able to isolate the compound, which can then be purified and sold commercially.

Popularity as a Solvent

One of the most popular uses is as an industrial cleaner or degreaser. It is very effective breaking molecules down and separating fats and lipids from other substances. From time to time it may be found in household cleaning products, too, but it is usually most common in solvents designed for use on heavy machinery or in places where a lot of space needs to be cleaned somewhat quickly. The solution isn’t normally very expensive, either, which is often a factor.

In Oil Processing

Many types of plants and vegetables are treated with this chemical in order to extract their oils and proteins for use in other products. Soybeans, peanuts, and corn are some of the most common. The compound is often able to break these foodstuffs down very efficiently, and the oils that result are typically ready to be repackaged and either sold or used in manufactured foods with very little additional treatment.

Common Applications

Hexane is commonly utilized as an industrial solvent used to manufacture products like paint thinner.

Industrial Applications

Hexane is often utilized to manufacture adhesives and similar products in which it acts as a strong cleaning agent. Hexane is also used as a cleaning agent during the manufacturing of the printing, textiles, and shoemaking industries. Hexane is present in glues used in shoemaking and roofing. It is also utilized for vegetable oil extraction from soybeans and other plants. This process is more environmentally friendly and more cost efficient than the traditional mechanical press method. Pure Hexane is not commonly used for vegetable oil extraction, but rather a mixture of isomers that comprise commercial Hexane. Hexane is utilized as a solvent and cleaning agent by the military and aerospace industries.

Consumer Applications

Consumer products containing Hexane include rubber cement, quick drying glues, gasoline, and paint remover.

Laboratory Applications

Hexane is often utilized as a solvent and reagent in laboratories. Sometimes solvents would need to be removed from lab reagents for the experiment being conducted. Rotary Evaporators or rotavapors are machines that are used to remove solvents like Hexane and Heptane from reaction mixtures. Rotary evaporators are common in most organic laboratories since they allow the removal to be performed swiftly and efficiently.

Hexane and Rotary Evaporators

Hexane and similar solvents like Heptane, Ethanol, Ethyl Acetate, Methanol, and Diethyl Ether, are removed from reaction mixtures by tools called Rotary Evaporators.

Other Common Uses

As good as it is at breaking compounds down, hexane can also be good at helping things stick together, particularly when used in conjunction with other non-water soluble compounds. It is often found listed as an ingredient in leather and shoe glue, for instance, and is sometimes used in roofing or tiling adhesives, too.

Controversy and Risks

Hexane is generally believed to be toxic or at least harmful when inhaled, and there have been instances of workplace injury and even death when people have spent long hours each day exposed to its fumes. This is most common in factories where oil extractions, industrial cleaning, or certain manufacturing operations take place. High exposure can cause skin irritation, dizziness, and nausea that progressively worsen over time.

There have also been questions about hexane residues that linger in vegetable oils, particularly when these show up in food products available in the general marketplace. Some health advocates argue that the presence of this chemical is unacceptable and dangerous, while others say that it is benign and shouldn’t be a cause for alarm. In most cases the amounts that actually end up in food are very, very small — but still, not a lot is known about how the compound behaves once ingested. Most of the toxicity studies that have been conducted have focused on inhalation and topical skin exposure.
Junyuan Petroleum Group reminds you that exposure to hexane without the right safety equipment can cause lasting damage and even death.

Industries where hexane is found

Several hundred million pounds of hexane are produced in the United States each year in the form of solvents. It is used as a cleaning agent in printing, shoe making, textiles, automotive brake repair, and furniture making. It is also used in the food industry.
Products where hexane is found
HexaneCommon household products, such as spray adhesives, contact cement, arts and craft paints, and stain removers contain hexane. The U.S. Department of Health and Human Services (HHS) Household Products Database lists 54 consumer products that contain hexane. Half of these products also contain solvents that increase the severity of hexane nerve damage. Although the majority of hexane containing products found on this list are used in the home, specifically for home maintenance, arts and crafts, and automotive products also contain it.
