CAS 110-82-7 Cyclohexane is a chemical substance called a cycloalkanes. Its chemical formula is C6H12. Cyclohexane is a nonpolar, colorless, flammable liquid with an odor similar to detergents and cleaning products. Cyclohexane Organic Solvent is primarily used in the industrial production of adipic acid and caprolactam, both key precursors in the manufacture of nylon.
What is Cyclohexanone CAS 110-82-7?
Cyclohexane is a saturated cyclic hydrocarbon with the chemical formula C₆H₁₂ and CAS number 110-82-7. It is a nonpolar compound with a molecular weight of 84.16 g/mol, composed of six carbon atoms in a cyclic structure, with each carbon atom bonded to two hydrogen atoms. It is also known as hexahydrobenzene, cycloalkanes, and hexamethylene, and its origins primarily lie in petroleum refining and benzene hydrogenation processes.
Cyclohexane liquid is insoluble in water but miscible with ethanol, acetone, benzene, and other organic compounds, making it both an important raw material and a commonly used solvent in various industrial applications.

How is cyclohexane Chemical produced?
All cyclohexane chemical is produced in benzene hydrogenation units. In the process, high-purity benzene feed and purified hydrogen (typically recovered from reformers and ethylene crackers) are brought to reaction temperatures and charged to the reactor. The conversion of benzene to cyclohexane is stoichiometric and almost complete; finished cyclohexane typically contains less than 50 ppm of benzene. A small amount of lower purity cyclohexane is recovered from petroleum streams by fractionation and extraction.
The Growing Use of Cyclohexane C6H12
Cyclohexane is in rising demand across global chemical industries.
- It is the core raw material for manufacturing Nylon 6 and Nylon 66.
- Fast growth in automotive, textile and construction sectors boosts nylon consumption, and further increases cyclohexane needs.
- Modern production technology improves its utilization efficiency.
- As downstream applications expand, cyclohexane usage will keep steady growth in the future.
