Cyclohexanol

Cyclohexanol is a saturated cyclic alcohol with the molecular formula C6H12O and CAS number 108-93-0. It consists of a six-membered cyclohexane ring with one hydroxyl (-OH) group attached. With a molecular weight of 100.16 g/mol, cyclohexanol appears as a colorless, viscous liquid or white crystalline solid at room temperature. It has a characteristic camphor-like odor and is classified as a secondary alcohol due to the hydroxyl group's position on the ring structure.

Cyclohexanol is a colorless to pale yellow liquid or white crystalline solid at room temperature with a melting point around 25°C and boiling point of 161°C. It has a distinctive camphor-like or menthol-like odor and is moderately soluble in water (approximately 3-4% by weight). The compound is readily soluble in most organic solvents including ethanol, ether, and acetone. It has a density of approximately 0.96 g/cm³ and exhibits typical alcohol properties including hydrogen bonding capabilities.

Cyclohexanol is primarily used as an intermediate in the production of adipic acid and caprolactam, which are essential raw materials for manufacturing nylon-6 and nylon-6,6 polymers. It serves as a solvent for lacquers, paints, and varnishes in various industrial applications. Additionally, cyclohexanol is utilized in the textile industry for fabric processing and as a chemical intermediate in the synthesis of plasticizers, pharmaceuticals, and other organic compounds. It also finds use in metal cleaning and degreasing operations.

Cyclohexanol requires careful handling due to its Acute Tox. 4, Skin Irrit. 2, and STOT SE 3 classifications with GHS07 pictogram. Wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin contact. Ensure adequate ventilation to avoid inhalation of vapors. Avoid contact with eyes, skin, and clothing. Use in well-ventilated areas away from ignition sources as it's classified as ADR Class 3 (flammable liquid). Handle containers carefully to prevent spills and always follow workplace safety protocols.

Cyclohexanol should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its flammable nature (ADR Class 3). Keep containers tightly closed and upright to prevent leakage. Store away from strong oxidizing agents and acids which may cause incompatible reactions. Maintain storage temperature below 25°C to prevent melting if stored as solid. Use appropriate secondary containment and ensure storage areas comply with local fire safety regulations for flammable liquids. Regularly inspect containers for signs of damage or deterioration.

Cyclohexanol contact requires immediate first aid measures due to its irritant properties. For skin contact, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush immediately with clean water for 15-20 minutes and remove contact lenses if present. For inhalation, move the person to fresh air immediately. If ingested, do not induce vomiting and seek medical attention. Always consult a physician if symptoms persist or in case of significant exposure.

Cyclohexanol disposal must comply with local, national, and EU waste regulations as it's classified as hazardous waste. The substance cannot be disposed of in regular waste streams or sewage systems due to its flammable and potentially harmful properties. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities may be suitable for solvent recovery programs. Always consult local environmental authorities for specific disposal requirements and ensure proper waste classification codes are used during the disposal process.

Cyclohexanol is classified under ADR Class 3 (flammable liquids), Packing Group III, requiring specific transport regulations compliance. Use appropriate packaging that meets UN specification requirements for Class 3 substances. Vehicles must carry proper hazard placards and documentation including transport documents with correct shipping names and hazard information. Drivers need ADR certification for dangerous goods transport. Ensure packages are properly sealed, labeled, and secured during transport. Follow routing restrictions and emergency response procedures as specified in ADR regulations.

Cyclohexanol is subject to several European regulations including REACH registration requirements for manufacturers and importers. It must be classified and labeled according to CLP Regulation with appropriate hazard statements and precautionary measures (GHS07 pictogram, Warning signal word). The substance is not currently listed as an SVHC (Substance of Very High Concern). Transport is regulated under ADR for dangerous goods. Workplace exposure limits may apply under occupational health regulations. Users must comply with national chemical safety legislation and maintain appropriate safety data sheets.
