Cyclohexanone is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: [11]. C 6 H 12 + O 2 → (CH 2) 5 CO + H 2 O. This process forms cyclohexanol as a by-product, and this mixture, called "KA Oil" for ketone-alcohol oil, is the main feedstock for the production of adipic acid.
2 and triethylborane generates the less substituted (and less stable) enolate. After reaction with methyl iodide the former mixture gives 2,2-dimethylcyclohexanone in 90% yield while the latter produces 2,6-dimethylcyclohexanone in 93% yield. [7] [8] The Et stands for ethyl group CH 3 CH 2 −.
Cyclohexenone is an organic compound which is a versatile intermediate used in the synthesis of a variety of chemical products such as pharmaceuticals and fragrances. [2] It is colorless liquid, but commercial samples are often yellow. Industrially, cyclohexenone is prepared from phenol by Birch reduction. [3]
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]

Cyclohexene is a hydrocarbon with the formula (CH 2) 4 C 2 H 2. It is an example of a cycloalkene. At room temperature, cyclohexene is a colorless liquid with a sharp odor. Among its uses, it is an intermediate in the commercial synthesis of nylon. [3]
