Properties

Chemical

Cyclohexane will burn in air to release water vapor and carbon dioxide.

Physical

Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products.

Availability

Cyclohexane is sold by chemical suppliers.

Preparation

Cyclohexane can be prepared via a Wurtz reaction of 1,6-dibromohexane.

Catalytic hydrogenation of benzene will also yield cyclohexane.

Projects

  • Organic extractions

Handling

Safety

Cyclohexane is flammable and should be handled with care. It is also harmful if inhaled, so wear proper protection.
