Cyclohexanone

Cyclohexanone is a colorless organic ketone with the chemical formula C6H10O and CAS number 108-94-1. It is a cyclic compound featuring a six-membered carbon ring with one ketone functional group. With a molecular weight of 98.14 g/mol, cyclohexanone is classified as a flammable liquid and presents moderate acute toxicity hazards, requiring appropriate safety precautions during handling and storage.

Cyclohexanone is a colorless to pale yellow liquid at room temperature with a characteristic sweet, acetone-like odor. It has excellent solvent properties and is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound is slightly soluble in water and exhibits moderate volatility. Its ketone structure makes it reactive toward nucleophiles and suitable for various chemical transformations.

Cyclohexanone is primarily used as an industrial solvent for resins, waxes, and rubber compounds. It serves as a key intermediate in the production of nylon-6 and nylon-6,6 through its conversion to caprolactam and adipic acid. Additional applications include paint strippers, wood stains, spot removers, and as a chemical intermediate in pharmaceutical and agrochemical synthesis.

Cyclohexanone requires careful handling due to its flammable and toxic properties. Essential safety measures include wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or use fume extraction systems to prevent vapor inhalation. Keep away from ignition sources, hot surfaces, and oxidizing agents. Always follow proper grounding procedures to prevent static electricity buildup.

Cyclohexanone should be stored in tightly closed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers grounded and use explosion-proof electrical equipment in storage areas. Store separately from strong oxidizing agents, strong bases, and incompatible materials. Maintain storage temperatures below 25°C and ensure adequate fire suppression systems are available in storage facilities.

In case of skin contact with cyclohexanone, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms persist.

Cyclohexanone disposal must comply with local and national hazardous waste regulations as it is classified as hazardous waste. The compound should be collected in appropriate containers and disposed of through licensed hazardous waste treatment facilities. Incineration at high temperatures with proper emission controls is typically the preferred disposal method. Never dispose of cyclohexanone down drains, sewers, or into the environment.

Cyclohexanone is classified under ADR as Class 3 (flammable liquids), Packing Group III, requiring specific transport regulations. It must be packaged in approved containers with proper labeling including GHS02 and GHS07 pictograms and 'Warning' signal word. Transport vehicles must carry appropriate safety equipment and documentation. Drivers require ADR certification for dangerous goods transport, and specific routing restrictions may apply.

Cyclohexanone is subject to various European regulations including REACH registration requirements and CLP classification as Flam. Liq. 3 and Acute Tox. 4. It is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with occupational exposure limits, safety data sheet requirements, and proper labeling according to GHS standards. Industrial users may need to implement risk management measures and worker protection programs.
