Hexane has been used for decades to extract edible oil from cottonseed. However, due to increased regulations affecting hexane because of the 1990 Clean Air Act and potential health risks, the oil-extraction industry urgently needs alternative hydrocarbon solvents to replace hexane. Five solvents,n-heptane, isohexane, neohexane, cyclohexane, and cylopentane, were compared with commercial hexane using a benchscale extractor. The extractions were done with a solvent to cottonseed flake ratio of 5.5 to 1 (w/w) and a miscella recycle flow rate of 36 mL/min/sq cm (9 gal/min/sq ft) at a temperature of 10 to 45°C below the boiling point of the solvent. After a 10-min single-stage extraction, commercial hexane removed 100% of the oil from the flakes at 55°C; heptane extracted 100% at 75°C and 95.9% at 55°C; isohexane extracted 93.1% at 45°C; while cyclopentane, cyclohexane, and neohexane removed 93.3, 89.4, and 89.6% at 35, 55, and 35°C, respectively. Each solvent removed gossypol from cottonseed flakes at a different rate, with cyclopentane being most and neohexane least effective. Based on the bench-scale extraction results and the availability of these candidate solvents, heptane and isohexane are the alternative hydrocarbon solvents most likely to replace hexane.

The Hexane Market is Segmented by Type (n-Hexane, Isohexane, Neohexane), Grade (Polymer Grade, Food Grade, Other Grades), Application (Industrial Solvents, Edible Oil Extractant, Adhesives and Sealants, Paints and Coatings, Other Applications), and Geography (Asia-Pacific, North America, Europe, South America, and Middle East & Africa).

Edible Oil Extraction to Dominate the Market

• Hexane is increasingly being used as a solvent to extract edible oils from seed and vegetable crops, e.g., peanuts, soybeans, corn, etc.
• Hexane has a greater ability to extract oil, compared to other solvents, like petroleum ether and ethyl acetate. It easily mixes with vegetable oil and washes it out without disturbing fiber, protein, sugar, and undesired gums.
• Growth in the edible oil segment can be attributed to the rising awareness among consumers about the use of refined oil and the impact it has on health.
• According to the United States Department of Agriculture, the consumption of edible oils like soybean oil, in 2019, in the United States, was 10,659 metric ton and canola oil was 2,465 metric ton. Moreover, according to the Department for Promotion of Industry & Internal Trade, in India, the investment value in the vegetable oil sector, in 2019, was around INR 18 billion.
• Additionally, the consumers are inclined to pay higher prices for healthy food products, owing to the increasing food-based health challenges, such as high cholesterol, obesity, etc.
• The growing popularity of edible oils with added health benefits in many countries is shaping the purchase decisions of edible oils, which are high in omega 3, vitamins, oryzanol, natural antioxidants, and others. Thus, exhibiting the likely demand for edible oils in the forthcoming years.

Use of leaching solvent in preparing edible fat and oil

A leaching solvent used for preparing edible oils is characterized in that the solvent is applied to the leaching process of edible oil preparation so as to leach oil from materials. The solvent consists of the following components by weight ratio: 94 to 100 percent of isohexane, 0 to 3 percent of normal hexane and 0 to 3 percent of butane and pentane; the leaching process includes the following steps of: 1) leaching: the leaching temperature is 48 to 53 DEG C and a mass ratio between the materials and solvent is 1/1 to 0.8; mixed oil and leached wet meal are obtained; 2) desolventizing: the finished meal is obtained; 3) the evaporation of a first long-tube; 4) the evaporation of a second long-tube; mixed oil is obtained; and 5) steam stripping: raw oil is obtained. The solvent of the invention is mainly composed of isohexane so as to largely reduce the harm to the health of operators exposed in the manufacturing environment; the product quality can be enhanced and the protection to environment can be enhanced; the latent heat for the evaporation of isohexane is low and then the energy cost required by the solvent recycling can be effectively reduced.

Corn oil (maize oil) is oil extracted from the germ of corn (maize). Its main use is in cooking, where its high smoke point makes refined corn oil a valuable frying oil. It is also a key ingredient in some margarines. Corn oil is generally less expensive than most other types of vegetable oils.

Corn oil is also a feedstock used for biodiesel. Other industrial uses for corn oil include soap, salve, paint, erasers, rustproofing for metal surfaces, inks, textiles, nitroglycerin, and insecticides. It is sometimes used as a carrier for drug molecules in pharmaceutical preparations.

Global n-Hexane market dynamics 

Demand for n-Hexane, especially in developing region such Asia Pacific, is expected to boost the demand of the global n-Hexane market over the forecast period. Excellent properties of n-Hexane to remove odor and unwanted taste are expected to propel the demand of n-Hexane from the edible oil industry. n-Hexane has the ability to remove unwanted taste and odor and this is the precise reason that the demand for n-Hexane has increased in edible oil industry. However, the consumers from developed regions are shifting from refined oil to cold-pressed oil owing to its superior health benefits. Cold pressing is a natural way to produce oil which does not contain solvent residues, no preservatives with natural antioxidants. In addition, Isohexane, a hexane isomer is used as a substitute of n-Hexane in few oilseed extraction applications. Due to toxic nature of n-Hexane, it has been substituted by n-heptane in some pharmaceutical applications. This may retard the growth of the n-Hexane market.

Almost all corn oil is expeller-pressed, then solvent-extracted using hexane or 2-methylpentane (isohexane). The solvent is evaporated from the corn oil, recovered, and re-used. After extraction, the corn oil is then refined by degumming and/or alkali treatment, both of which remove phosphatides. Alkali treatment also neutralizes free fatty acids and removes color (bleaching). Final steps in refining include winterization (the removal of waxes), and deodorization by steam distillation of the oil at 232–260 °C (450–500 °F) under a high vacuum.

Some specialty oil producers manufacture unrefined, 100%-expeller-pressed corn oil. This is a more expensive product since it has a much lower yield than the combination expeller and solvent process, as well as a smaller market share.

2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C₆H₁₄. It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain.

What is Isohexane used for?
A clear, colourless liquid commonly used as a constituent of gasoline and glues used for shoes, leather products and roofing. Additionally, it is used in solvents to extract oils for cooking and as a cleansing agent for shoe, furniture and textile manufacturing.

What is 2 Methylpentane used for?
2–Methylpentane is an alkane. Methyl pentane appears as colorless liquid. Isomers (2-methyl, 3-methyl) are possible and present in technical mixtures or singly for research purposes. Used in organic synthesis and as a solvent.

Does hexane or 2 Methylpentane have a higher boiling point?
The more symmetrical the molecules are, the easier it will be and the fewer spaces there will be between the molecules. Fewer spaces = better stacking. Hence, when you compare hexane to its structural isomer, 2–methylpentane, hexane has a much higher melting point due to the regular arrangement of its structure.

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.
