Cyclohexene

Cyclohexene is an unsaturated cyclic hydrocarbon with the molecular formula C6H10 and CAS number 110-83-8. It consists of a six-membered carbon ring containing one double bond, making it a cycloalkene. With a molecular weight of 82.14 g/mol, cyclohexene is an important intermediate in organic chemistry and industrial processes. It appears as a colorless liquid at room temperature and is characterized by its reactive double bond, which makes it valuable for various chemical syntheses and transformations.

Cyclohexene is a colorless liquid with a characteristic sweet, gasoline-like odor at room temperature. It has a boiling point of approximately 83°C and a density of about 0.81 g/cm³. The compound is practically insoluble in water but readily soluble in organic solvents such as alcohol, ether, and benzene. Its unsaturated nature due to the C=C double bond makes it reactive towards addition reactions, oxidation, and polymerization processes under appropriate conditions.

Cyclohexene serves as an important intermediate in the chemical industry for manufacturing various organic compounds. It is primarily used in the production of cyclohexanol and cyclohexanone, which are precursors for nylon synthesis. Additionally, cyclohexene finds applications in the manufacture of synthetic rubber, pharmaceuticals, and as a solvent in organic synthesis. It is also utilized in research laboratories as a reagent for organic transformations and as a starting material for the preparation of specialized chemicals.

Cyclohexene should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent vapor accumulation. Avoid contact with skin, eyes, and inhalation of vapors. Keep away from heat sources, sparks, and open flames as cyclohexene is flammable. Use non-sparking tools and ensure proper grounding when transferring the material to prevent static electricity buildup.

Cyclohexene should be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from heat sources and direct sunlight. Storage temperature should be kept below 25°C to minimize vapor pressure and potential hazards. Keep containers away from oxidizing agents, acids, and bases which may react with the double bond. Store in approved flammable liquid storage cabinets when possible, and ensure adequate fire prevention measures are in place in the storage area.

In case of skin contact with cyclohexene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, rinse eyes immediately with clean water for at least 15 minutes and seek medical attention. If vapors are inhaled, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a medical professional for proper evaluation and treatment.

Cyclohexene must be disposed of in accordance with local, national, and international environmental regulations. It should never be poured down drains or disposed of in regular waste. The material should be collected in appropriate containers and handed over to licensed waste management companies for proper treatment or incineration. Small laboratory quantities may be subjected to controlled combustion in approved facilities. Always consult local environmental authorities for specific disposal requirements and approved waste handlers.

Cyclohexene is classified as ADR Class 3 (Flammable Liquids), Packing Group II, requiring specific transport regulations compliance. It must be packaged in UN-approved containers suitable for flammable liquids and properly labeled with appropriate hazard placards. Transport vehicles must be equipped with appropriate fire extinguishing equipment and drivers must hold ADR certification. The material should be secured to prevent container damage during transport and kept away from heat sources and incompatible materials during shipment.

Cyclohexene is regulated under various chemical legislation frameworks including REACH in Europe, where it must be registered for commercial use above certain tonnage thresholds. It is not classified as a Substance of Very High Concern (SVHC) under REACH. The compound falls under workplace safety regulations requiring appropriate risk assessments and safety measures. Transport is regulated under ADR/RID for road and rail transport. Users must comply with local occupational health and safety requirements and environmental protection standards.
