Cyclohexanol is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: [5]. 2 C 6 H 12 + O 2 → 2 C 6 H 11 OH. This process coforms cyclohexanone, and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid.
C=C Pi bond. An E1 reaction is the Ionization of the carbon-halogen bond breaking to give a carbocation intermediate, then the Deprotonation of the carbocation. For these two reactions, there are 3 possible products, 3-methyl-cyclohexene,1-methyl-cyclohexene, methylene-cyclohexane.
It can be produced by a Wittig reaction or a reaction with a Tebbe's reagent from cyclohexanone. [1] [2] [3] It can also be synthesized as a side product of the dehydration of 2-methylcyclohexanol into 1-methylcyclohexene.
It has been patented for use in air fresheners. [8]U.S. Patent 4915825 describes a froth flotation process for cleaning coal where a mixture of 95% MCHM, 4% water, and 0.1% 4-methylcyclohexanemethanol monoether (such as 4-(methoxymethyl)cyclohexanemethanol) is used as a frothing agent, and finely divided coal particles adhere to air bubbles induced into the agent which rise to the surface.

[4] The conversion of methylcyclohexane to toluene is a classic aromatization reaction. This platinum (Pt)-catalyzed process is practiced on scale in the production of gasoline from petroleum. [10] It is also one of a host of substances in jet fuel surrogate blends, e.g., for Jet A fuel. [11] [12]
Cyclohexene is produced by the partial hydrogenation of benzene, a process developed by the Asahi Chemical company. [4] The main product of the process is cyclohexane because cyclohexene is more easily hydrogenated than benzene. In the laboratory, it can be prepared by dehydration of cyclohexanol. [5] C 6 H 11 OH → C 6 H 10 + H 2 O
A copper chromite catalyst is usually used industrially. [1] The cis/trans ratio of the CHDM is affected by the catalyst. [2] Byproduct of this process are 4-methylcyclohexanemethanol (CH 3 C 6 H 10 CH 2 OH) and the monoester methyl 4-methyl-4-cyclohexanecarboxylate (CH 3 C 6 H 10 CO 2 CH 3, CAS registry number 51181-40-9).
