Cyclohexane

Cyclohexane: An Industrial Guide to Properties, Applications, and Global Supply Chains

Cyclohexane (C₆H₁₂). Often referred to in systematic nomenclature as hexamethylene, cyclohexane is a cycloalkane that serves as the backbone for the global nylon industry. As the primary precursor for the production of adipic acid and caprolactam, its role in the manufacturing of synthetic fibers, resins, and polymers is irreplaceable.

At ChemicalsSuppliers.com, we bridge the gap between chemical manufacturers and industrial end-users. This guide provides an exhaustive look into the chemical nature, safety protocols, market dynamics, and procurement strategies for cyclohexane and its related derivatives.


1. Defining Cyclohexane: Chemical Profile and Nomenclature

Cyclohexane is a colorless, flammable liquid with a mild, sweet odor. It belongs to the class of cycloalkanes—saturated hydrocarbons in which the carbon atoms are connected in a ring.

Systematic and Common Synonyms

To navigate global procurement effectively, one must recognize the various names used in technical documentation and international trade:

  • IUPAC Name: Cyclohexane
  • Common Synonyms: Hexamethylene, Hexahydrobenzene, Naphthene.
  • CAS Number: 110-82-7
  • Molecular Formula: C₆H₁₂
  • InCHI: 1S/C6H12/c1-2-4-6-5-3-1/h1-6H2

Physical and Chemical Properties

Understanding the physical state of cyclohexane is vital for storage and transportation:

  • Boiling Point: 80.7 °C (177.3 °F)
  • Melting Point: 6.5 °C (43.7 °F)
  • Density: 0.779 g/cm³ at 20 °C
  • Solubility: Practically insoluble in water; highly soluble in organic solvents like ethanol, ether, and benzene.
  • Flammability: Highly flammable liquid and vapor (Flash point: -18 °C).

2. Industrial Production: How Cyclohexane is Manufactured

The primary method for producing cyclohexane is the catalytic hydrogenation of benzene. This reaction follows the chemical equation: C₆H₆ (Benzene) + 3H₂ (Hydrogen) → C₆H₁₂ (Cyclohexane)

This reaction is carried out in the presence of metallic catalysts (such as nickel or platinum) under precise pressure and temperature conditions. The purity requirements for cyclohexane are extremely high, especially when it acts as an intermediate for polymerization.


3. Key Applications of Cyclohexane

Why is there such high global demand? The answer lies in its derivative chain.

The Nylon Pipeline

Approximately 80% to 90% of global cyclohexane production is consumed in the manufacture of adipic acid and caprolactam. These are the dual precursors to Nylon 6 and Nylon 6,6.

  • Nylon 6,6: Used in textiles, automotive airbags, and industrial cords.
  • Nylon 6: Extensive use in carpets, engineering plastics, and packaging films.

Solvent Applications

Beyond polymers, cyclohexane is a highly effective solvent. It is used in:

  • Adhesives and Sealants: Used in the production of rubber-based contact cements.
  • Paints and Coatings: Acts as a carrier solvent for resins.
  • Extraction Processes: Used in the extraction of essential oils and pharmaceutical purification.
  • Recrystallization: A standard reagent in chemical laboratories for purifying organic compounds.

4. Safety, Handling, and Environmental Regulations

Because cyclohexane is a volatile organic compound (VOC), handling protocols must strictly adhere to OSHA and REACH standards.

  • Hazard Identification: Cyclohexane is classified as highly flammable. It poses risks for skin irritation and, if inhaled in large concentrations, central nervous system depression.
  • Storage Requirements: Must be stored in cool, well-ventilated areas away from sparks or open flames. Use grounded containers to prevent static discharge.
  • PPE: Nitrile gloves, safety goggles, and respiratory protection are mandatory in industrial handling environments.
