Apr 07, 2026 Leave a message

Organic chemical cyclohexane (C6H12) is a clear, colorless liquid with a CAS number of 110-82-7; it is highly flammable and possesses a faint, petroleum-like odor. Due to its non-polar properties, it is well-suited for dissolving a diverse array of organic compounds. Cyclohexane is used as a solvent and industrial raw material, playing a critical role in the manufacture of nylon.

 

What Is Cyclohexane Solvent (CAS No 110 82 7)

Cyclohexane (CAS No. 110-82-7) is a colorless, non-polar and highly flammable liquid with a characteristic sweet smell. It is a cyclic alkane mainly produced by hydrogenating benzene or directly from petroleum fractions. Its stable ring structure makes it a valuable solvent and intermediate for many chemical synthesis processes.

Key Applications of Cyclohexane C6H12 Solvent

The majority of the cyclohexane solvent produced globally is utilized in the manufacture of nylon. This constitutes its primary and most significant application, accounting for the largest share of total production output. When cyclohexane undergoes oxidation through industrial processes, it yields two key chemical compounds: cyclohexanone and cyclohexanol. These two substances serve as vital intermediates in the production of adipic acid and caprolactam-materials that are absolutely indispensable for the manufacture of Nylon-6 and Nylon-6,6. In short, cyclohexane solvent is an absolutely essential component of the modern nylon supply chain.

Beyond its primary role in nylon production, cyclohexane chemical possesses a number of other important and practical applications across various sectors.

 

1. Calibration Solvent in Laboratory Experiments

In a wide range of laboratory testing and analytical procedures, cyclohexane solvent is frequently employed as a calibration solvent. Specifically, in chromatographic analysis experiments, it is used to adjust and verify the accuracy of the instrumentation.

 

2. Reference Substance for Determining Fuel Octane Ratings

Within the fuel industry, cyclohexane solvent serves as a crucial reference substance for determining the octane ratings of gasoline and other fuels. By utilizing cyclohexane as a reference standard, engineers and technicians are able to accurately test and evaluate the octane performance of various fuel blends.

 

3. Volatile Solvent in Adhesives and Coatings

CAS No. 110-82-7 Cyclohexane is also widely utilized as a volatile solvent in the manufacturing processes of adhesives, paints, and coatings. Possessing exceptional solvency, it efficiently dissolves the various resins and other raw materials required in the formulations of these products. Furthermore, it evaporates rapidly, thereby facilitating faster drying and film formation. This not only enhances production efficiency but also ensures the quality and performance of the final products.

Frequently Asked Questions (FAQ)

Q: What are the main applications of Cyclohexane solvent?

A: Cyclohexane is mainly used to make adipic acid and caprolactam, which are important materials for producing nylon‑6 and nylon‑6,6. It is also used as an industrial solvent for paints, coatings, cleaning.

Q: Is Cyclohexane (CAS 110-82-7) aromatic?

A: No, cyclohexane is not aromatic. It has a six‑membered ring but no delocalized π electrons, unlike benzene which is aromatic.

Q: Is Cyclohexane polar or nonpolar?

A: It is nonpolar. The bonds between carbon and hydrogen are almost nonpolar, and the molecule is symmetric, so it has no overall dipole.

Q: Is Cyclohexane hazardous?

A: Yes. Cyclohexane liquid is flammable. Breathing it in may make you dizzy or sleepy. Long‑term exposure can be harmful, and it is toxic to aquatic life. You need safe handling, protective gear, and good ventilation.
