Chemical Properties:
1. It is relatively stable to acids and alkalis, and does not react with medium concentrations of nitric acid or mixed acid at low temperatures. It undergoes nitration reaction with dilute nitric acid in a sealed tube above 100°C to form nitrocyclohexane . Under platinum or palladium catalysis, a dehydrogenation reaction occurs above 350°C to form benzene. Together with aluminum oxide , molybdenum sulfide, cobalt, nickel and aluminum, isomerization occurs at high temperature to form methylpentan . Isomerized with aluminum trichloride to methylcyclopentane under mild conditions。
2. Cyclohexane can also undergo an oxidation reaction , and the main products obtained are different under different conditions. For example, when oxidizing at 185-200°C and 10-40 with air atmospheric pressure , 90% cyclohexanol is obtained. If the cobalt salt or manganese salt of the fatty acid is used as the catalyst at 120-140°C and 18-24 atmospheres and oxidized with air, a mixture of cyclohexanol and cyclohexanone is obtained . with air, Direct oxidation of cyclohexane concentrated nitric acid or nitrogen dioxide at high temperatures to obtain adipic acid . In of palladium, molybdenum, chromium, and manganese , gas phase oxidation is performed to obtain the presence of oxides maleic acid . Under sunlight or ultraviolet light , it acts with halogen to form halides . Reaction with nitrosyl chloride to produce cyclohexanoxime. Aluminum trichloride is used as a catalyst to react cyclohexane with ethylene to form ethylcyclohexane , dimethylcyclohexane , diethylcyclohexane, tetramethylcyclohexane, etc.
