Overview
Cyclohexene is a cyclic hydrocarbon with one double bond, classified as a cycloalkene. It serves as a versatile intermediate in industrial chemistry, particularly in nylon production. The compound is synthesized via partial hydrogenation of benzene or dehydration of cyclohexanol. As a building block, it is valued for its reactivity in Diels-Alder reactions and hydrogenation processes. Commercial grades typically exceed 98% purity, with stabilizers added to prevent polymerization during storage.
Physical and Chemical Properties
Cyclohexene exhibits typical alkene characteristics, including susceptibility to electrophilic addition reactions. Its volatility (vapor pressure: 72 mmHg at 20°C) requires careful handling to prevent inhalation exposure. The liquid has a faint, sweet odor detectable at 0.18 ppm. The compound's ring strain and electron-rich double bond make it more reactive than linear alkenes. It undergoes halogenation, epoxidation, and hydroformylation readily. Thermal decomposition occurs above 300°C, producing hazardous gases like carbon monoxide.
Main Applications
Over 60% of global cyclohexene production is used to manufacture adipic acid through oxidation, a key precursor for nylon 6,6. It also serves as a reactive diluent in specialty coatings and a chain transfer agent in polymer chemistry. In laboratory settings, it functions as a model substrate for studying catalytic hydrogenation mechanisms. Emerging applications include use in lithium-ion battery electrolytes and pharmaceutical intermediates where its derivatization potential is exploited.
Safety and Storage
As a Category 3 flammable liquid (NFPA), cyclohexene requires storage in UN-approved containers with flame arrestors. Bulk storage tanks should have nitrogen blanketing to prevent peroxide formation. Grounding and bonding are essential during transfer operations. Personal protective equipment (PPE) must include chemical goggles, neoprene gloves, and respiratory protection above exposure limits (10 ppm TWA). Spills should be contained with non-combustible absorbents like vermiculite, never washed into drains.
B2B Procurement Guide
Industrial buyers should specify technical grade (≥98%) or purified grade (≥99.5%) depending on application needs. Common packaging includes 200L steel drums (net 160kg) or isotanks (20MT capacity). Verify supplier compliance with ISO 9001 and Responsible Care® standards. Key quality indicators include peroxide content (<0.1%) and water content (<0.05%). Long-term contracts often secure better pricing, with typical MOQs of 5MT for drum shipments.
