N-hexane is an organic compound (hydrocarbon) composed of carbon and hydrogen elements. Hexane is an unbranched isomer (n-hexane). Isomers are compounds that exist in the form of different atomic configurations but with the same molecular weight. Hexane is an important component of gasoline, which is a common and well-known liquid mixture derived from petroleum, mainly used as fuel for internal combustion engines. Hexane is widely used as an inexpensive, relatively safe, primarily inert and volatile non-polar solvent.
Properties of n-hexane
We list the main physical properties of hexane: the molecular formula of hexane is C6H14. Hexane is essentially a colorless liquid. The melting point of hexane is approximately -139.54 ° F (-95.3 ° C). The boiling point of hexane is 154.04 ° F (67.8 ° C). The molecular weight of hexane is 86.18 grams per mole (g/mol). Hexane is a non-polar molecule, which means it is insoluble in water.
The structural formula of n-hexane
Hexane is an alkane with six carbon atoms. Alkanes (also known as paraffin or saturated hydrocarbons) are compounds composed solely of carbon (C) and hydrogen (H) elements (i.e. hydrocarbons), in which atoms are connected to each other only by single bonds. Hexane is a relatively simple molecule. The prefix 'hex' indicates that hexane has six carbon atoms. These carbons are followed by 14 hydrogens, forming the molecular formula C6H14. All carbon atoms are connected in a row, one after another. Each carbon atom, except for the first and last, has at least two hydrogen atoms connected to it. Three hydrogen atoms are connected to the first and last carbon atoms.
Production of n-hexane
Hexane is mainly produced during the refining process of crude oil, which is a naturally occurring flammable liquid composed of a complex mixture of hydrocarbons. The exact composition of fractions largely depends on the source of crude oil and the degree of processing or refining.
Application of n-hexane
The most successful use of hexane is its function as a solvent. Many types of plants and vegetables (such as soybeans, peanuts, and corn) are treated with hexane to produce oils, fats, and proteins for other products. Hexane is also used as a cleaning solvent and for industrial degreasing and cleaning purposes.
How to reduce the risks associated with the use of n-hexane
Some household products may contain hexane. Among these products, such as some quick drying adhesives and cement, of course, such products should be stored out of reach of children. In addition, it is highly necessary to have a good ventilation system and ventilate rooms that use or contain products containing hexane more frequently. Conversely, in the industrial sector, high-quality cleaning systems and various specialized filters should be used. Under the constraints of all simple safety measures, all risks are minimized, and the production and use of hexane have become almost completely safe.
