Cyclohexanone production process:
Commercial production of this material can be done using different methods
-Hydrogenation of benzene is in a closed system
-It is prepared from the oxidation of cyclohexanol by chromic acid. In this process, chromic acid is obtained from a mixture of sodium bicarbonate or potassium bicarbonate and sulfuric acid.
-Hydrogenation of phenols
C6H5OH + 2 H2 → (CH2)5CO
-Cyclohexanone is also prepared from the oxidation of cyclohexane in the air in the presence of a cobalt catalyst.
C6H12 + O2 → (CH2)5CO + H2O
-Catalytic dehydrogenation of cyclohexanol
C6H11OH → C6H11OH + H2
-Cyclohexanone can be prepared from the oxidation of cyclohexanol with chromium trioxide called the Jones oxidation process.
