Cyclohexane (CAS 110-82-7) is a high-purity cycloalkane widely used as a key industrial solvent and essential precursor in the production of nylon and other high-performance materials. Also known as hexahydrobenzene or hexamethylene, this clear, colorless liquid with a mild petroleum-like or sweet odor plays a critical role in modern chemical manufacturing processes.

Product Overview

Chemical Name: Cyclohexane

CAS Number: 110-82-7

Molecular Formula: C₆H₁₂

Molecular Weight: 84.16 g/mol

Appearance: Colorless clear liquid

Solubility: Insoluble in water; fully miscible with most organic solvents (alcohols, ethers, hydrocarbons, acetone, benzene)

Key Applications

Cyclohexane is a foundational building block and solvent in several major industrial sectors:

  • Nylon Production — Primary feedstock for producing cyclohexanone, cyclohexanol (KA oil), adipic acid, and caprolactam, which are essential intermediates for manufacturing nylon-6 and nylon-6,6 used in textiles, carpets, automotive parts, engineering plastics, tire cords, and industrial fibers.
  • Solvent Applications — Widely employed as a non-polar solvent in adhesives, paints, varnishes, lacquers, resins, fats, oils, waxes, bitumen, and rubber processing; also used in paint strippers, correction fluids, and extraction of essential oils.
  • Chemical Synthesis — Serves as a starting material for producing cyclohexyl derivatives, plasticizers, synthetic lubricants, polyurethanes, and various fine chemicals.
  • Other Industrial Uses — Functions in laboratory analysis, recrystallization processes, solid fuel formulations (e.g., camp stove fuels), and as a substitute for benzene in many applications due to its favorable safety profile.

Over 90% of global cyclohexane production supports nylon intermediate manufacturing, making it indispensable for the polymer and textile industries.

Technical Advantages

  • Superior solvency for non-polar substances without the higher toxicity of aromatics like benzene
  • High purity grades available for consistent performance in downstream reactions
  • Low water solubility and excellent compatibility with organic systems
  • Volatile nature suitable for processes requiring easy evaporation or recovery
  • Established, reliable supply chain for large-scale industrial consumption

Safety & Handling Information

Cyclohexane is classified as a highly flammable liquid (Category 2) and poses an aspiration hazard. It causes skin irritation, may cause drowsiness or dizziness, and is harmful if inhaled or swallowed (can enter airways and cause serious lung damage). Vapors are heavier than air and can form explosive mixtures with air. Use explosion-proof equipment, adequate ventilation, and appropriate PPE (chemical-resistant gloves, goggles, protective clothing, and respiratory protection where needed). Store in tightly sealed containers in a cool, well-ventilated area away from ignition sources, strong oxidizers, and acids. Prevent static buildup. Always consult the current Safety Data Sheet (SDS) for detailed hazard information, first-aid measures, firefighting guidance, and proper disposal procedures.

Frequently Asked Questions (FAQs)

What is the main industrial use of Cyclohexane CAS 110-82-7? The majority is oxidized to produce KA oil (cyclohexanone and cyclohexanol), which is then converted into adipic acid and caprolactam for nylon-6 and nylon-6,6 production.

Is Cyclohexane soluble in water? No, it is practically insoluble in water but mixes completely with most common organic solvents, making it ideal as a non-polar solvent.

Why is Cyclohexane preferred over benzene in many applications? It offers similar solvency with a better safety and regulatory profile (lower toxicity and no classification as a known carcinogen).

What industries depend heavily on Cyclohexane? Textiles and fibers (nylon), plastics and polymers, paints and coatings, adhesives, rubber processing, and chemical intermediate manufacturing.

Is Cyclohexane flammable? Yes, it is highly flammable with a very low flash point (-20 °C) and forms explosive vapor-air mixtures; strict fire prevention measures are required.

Can Cyclohexane be used in food or pharmaceutical final products? No, it is an industrial solvent and intermediate, not approved for direct food contact, pharmaceutical formulations, or consumer products.

What packaging formats are available for Cyclohexane? Common options include drums, IBC totes, iso-tanks, and bulk shipments — contact us for exact availability, grades, and volumes.
