    N-Pentane, a chemical formula C5H12, the fifth member of an alkane. N-pentane has two isomers: isopentane (boiling point 28 ° C) and neopentane (boiling point 10 ° C), the term "pentane" usually refers to n-pentane, its linear isomer .
    Usage of normal pentane
    1. It is used as a low boiling point solvent, a plastic industrial foaming agent, and is also used together with 2-methylbutane as a fuel for automobiles and airplanes, for manufacturing artificial ice, an anesthetic, for synthesizing pentanol, isopentane, and the like.

    N-hexane is a colorless liquid with low toxicity and a weak special odor. N-hexane is a chemical solvent mainly used as a solvent for olefin polymerization such as propylene, an extractant for edible vegetable oil, a solvent for rubber and paint, and a diluent for pigments. It has certain toxicity and will enter the human body through the respiratory tract and skin. Long-term exposure can lead to chronic poisoning symptoms such as headache, dizziness, fatigue, and numbness in the limbs, which can lead to fainting, loss of consciousness, cancer and even death.

    N-hexane production process
    Most of the foreign hexane production uses molecular sieve adsorption processes, such as Richfielcd (Richfield) and Watson (Watson) in the United States, using reconstituted raffinate as raw material, by recycling two or more beds for adsorption. Press desorption to produce n-hexane.
    Most domestic hexane manufacturers use the hydrogenation distillation process, which is divided into two types:

    First, hydrogenation then rectification.

    Main use of n-hexane
     
    N-hexane is a good non-toxic organic solvent, widely used in vegetable oil extraction, butyl, butadiene rubber organic synthesis, propylene, olefin polymerization, pharmaceutical intermediates, paint thinners, and metal surface cleaning of mechanical equipment.

    Development and main application of n-hexane
     
    The main market for n-hexane is used in the vegetable oil leaching industry, which accounts for more than 60% of the total amount of n-hexane. Most of the remaining applications are in the rubber and chemical industries.
