n-Hexane

n-Hexane is a saturated, straight-chain aliphatic hydrocarbon (or alkane) with the general formula C_nH_2n+2 and one of a series of hydrocarbons with low boiling points (between 40 and 90 °C) obtainable from petroleum by various processes (cracking, reforming). These hydrocarbons are a mixture of alkanes and cycloalkanes with five to seven carbon atoms (n-pentane, n-hexane, n-heptane, isopentane, cyclopentane, 2-methylpentane, 3-methylpentane, cyclohexane, methylcyclopentane). Their fractional distillation produces single hydrocarbons that may be of varying degrees of purity.

Hexane is sold commercially as a mixture of isomers with six carbon atoms, boiling at 60 to 70 °C. The isomers most commonly accompanying it are 2-methylpentane, 3-methylpentane, 2,3-dimethylbutane and 2,2-dimethylbutane. The term technical hexane in commercial use denotes a mixture in which are to be found not only n-hexane and its isomers but also other aliphatic hydrocarbons with five to seven carbon atoms (pentane, heptane and their isomers).

Hydrocarbons with six carbon atoms, including n-hexane, are contained in the following petroleum derivatives: petroleum ether, petrol (gasoline), naphtha and ligroin, and fuels for jet aircraft.

n-Pentane is an organic compound with the chemical formula of C5H12. It is the fifth member of alkanes and is often used as a solvent. Pentane is an aliphatic saturated hydrocarbon with stable chemical properties. It does not react with acid and alkali under normal temperature and pressure. Pyrolysis occurs at high temperature above 600 ℃ or in the presence of appropriate catalyst to produce mixtures of propylene, butene, isobutylene, butane and isopropane. The physical properties of n-Pentane, Isopentane and neopentane are not different, and the chemical properties are different due to their structural differences There are two isomers of n-Pentane: Isopentane and neopentane. The term “pentane” usually refers to n-Pentane, that is, its linear isomer. “Normal” generally refers to the straight chain structure, for example, “n-” Pentane is straight chain “ISO” generally refers to a branched chain structure, for example, Isopentane is 2 – methylbutane “New” generally refers to the isomer with two branched chain structures. For example, neopentane is 2,2-dimethylpropane and above are all pentane.

Yes, there are. Junyuan Petroleum Group can make many different grades of our hexanes to satisfy the client’s requirements for purity. For example, several products, such as extra pure n-Hexane have a super-pure grades for the pharmaceuticals, reagent and biotech industries. This means the accuracy of the blending, the nonvolatile residues and water content are all exactly where you want them, and this information is included on the Normal Hexane Product Specs.

Product Information
 
Pentane is an organic compound with the formula C5H12 — that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer; the other two being called “methylbutane” and “dimethylpropane”. Cyclopentane is not an isomer of pentane. Pentanes are components of some fuels and are employed as specialty solvents in the laboratory. Their properties are very similar to those of butanes and hexanes.

Applications

2-Methylbutane is used as a chemical intermediate. It acts as a blowing agent for polystyrene and gasoline additive. It is used as a solvent of polyethylene and involved in the preparation of polystyrene foam and polyurethane foam. Further, it is used in a closed loop in geothermal power production to operate turbines. In addition to this, it is used to freeze biological samples like tissues in place of dry ice for cryosectioning in histology.

Isopentane is suggested to maximise the ORC electric efficiency.

Notes

Store in a cool place. Incompatible with rubber, plastics and oxidizing agents.

In crude oil refineries, organic solvents are produced as volatile fractions. The hydrocarbon solvent contains alkanes, cycloalkanes and aromatic components in different proportions. Aliphatic solvents and aromatic solvents. The molecules of the aliphatic solvent have a straight chain structure. Hexane (c6h14), gasoline (gasoline, benzene) and kerosene are aliphatic solvents. Aliphatic solvents are used for oil extraction, degreasing, rubber and paint manufacturing, and as carriers of aerosols and disinfectants. A medium heavy aliphatic solvent produced from distillates of crude oil. These types of compounds have hydrocarbon molecular compositions of different lengths, which makes them suitable for various application fields.

Hexane is part of our series of special boiling point (SBP) aliphatic hydrocarbon solvents for de aromatization. These high purity fluids have a stable composition and a fixed narrow boiling point range, so they are particularly suitable for applications or industrial process conditions that require specific evaporation / drying performance. The main application fields include polymerization process, professional coatings and adhesives, pharmaceutical and food extraction process, industrial cleaning and degreasing, textile and rubber manufacturing, and catalyst preparation.

Heptane is a colorless liquid with low odor, medium boiling range and very narrow boiling range. It has relatively low odor and rapid drying characteristics. It can dissolve many organic compounds and evaporate easily, which means that it is used as a solvent or diluent in a wide range of industrial applications. The main application fields include polymerization process, professional coatings and adhesives, pharmaceutical extraction process, industrial cleaning and degreasing, textile and rubber manufacturing. Most importantly, catalyst preparation is one of the key applications.

Pentane is a group of high-purity aliphatic hydrocarbon solvents, including n-pentane and isopentane and mixtures of these two components. N-pentane is very suitable as blowing agent and propellant in polymerization process. Pentane plays a fundamental role in the production of polystyrene and polyurethane foams. It is a foaming agent, which helps to expand raw plastic materials and form honeycomb structure in foam, giving excellent thermal performance. In the polymerization process, pentane acts as a diluent, dissolves components and assists reactions between other chemicals without interfering with the polymerization process.

The molecules of the pure aromatic solvent have a benzene ring structure, such as benzene (C6H6), toluene (C6H5CH3), and xylene (C8H10). Pure (high) aromatic solvents are used for degreasing, as diluents, and in the manufacture of paints, printing inks, pesticides and agricultural chemicals.
