Cyclohexane (English name: Cyclohexane) is a colorless liquid with a gasoline odor. It is insoluble in water and can be miscible with various organic solvents such as ethanol, ether, acetone, benzene, etc. The solubility in methanol is 57 parts of cyclohexane for 100 parts of methanol (25°C). It is volatile and flammable, with a flash point of 18°C. The vapor forms an explosive mixture with air, and the explosion limit is 1.3-8.3% (volume). It is relatively stable to acids and alkalis. It does not react with medium concentrations of nitric acid or mixed acids at low temperatures. It undergoes nitration reaction with dilute nitric acid in a sealed tube above 100°C to produce nitrocyclohexane. Under the catalysis of platinum or palladium, dehydrogenation reaction occurs above 350°C to produce benzene. It isomerizes with aluminum oxide, molybdenum sulfide, copper, and nickel-aluminum at high temperatures to produce methylpentane. It isomerizes with aluminum trichloride under mild conditions to methylcyclopentane.
