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).

The original publication concerns the conversion of bile acid in a series of reactions: acid chloride (2) formation with thionyl chloride, diazoketone formation (3) with diazomethane, chloromethyl ketone formation (4) with hydrochloric acid, organic reduction of chlorine to methylketone (5), ketone halogenation to 6, elimination reaction with ...
Most methylcyclohexane is extracted from petroleum but it can be also produced by catalytic hydrogenation of toluene: CH 3 C 6 H 5 + 3 H 2 → CH 3 C 6 H 11. The hydrocarbon is a minor component of automobile fuel, with its share in US gasoline varying between 0.3 and 1.7% in early 1990s [10] and 0.1 to 1% in 2011. [11]
Compared with its isomer cyclohexa-1,4-diene, cyclohexa-1,3-diene is about 1.6 kJ/mol more stable. [5] Cyclohexadiene and its derivatives form (diene)iron tricarbonyl complexes. Illustrative is [(C 6 H 8)Fe(CO) 3], an orange liquid. This complex reacts with hydride-abstracting reagents to give the cyclohexadienyl derivative [(C 6 H 7)Fe(CO) 3 ...
The silver salt 1 reacts with bromine to form the acyl hypohalite intermediate 2. Formation of the diradical pair 3 allows for radical decarboxylation to form the diradical pair 4, which recombines to form the organic halide 5. The trend in the yield of the resulting halide is primary > secondary > tertiary. [2] [3]
[1] The general chemical formula of the halogen addition reaction is: C=C + X 2 → X−C−C−X (X represents the halogens bromine or chlorine, and in this case, a solvent could be CH 2 Cl 2 or CCl 4). The product is a vicinal dihalide. This type of reaction is a halogenation and an electrophilic addition.
1,4-Cyclohexadiene is an organic compound with the formula C 6 H 8. It is a colourless, flammable liquid that is of academic interest as a prototype of a large class of related compounds called terpenoids, an example being γ-terpinene. An isomer of this compound is 1,3-cyclohexadiene.
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.
