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 −.
2,5-Dimethylhexane is a branched alkane used in the aviation industry in low revolutions per minute helicopters. [2] As an isomer of octane , the boiling point is very close to that of octane, but can in pure form be slightly lower. 2,5-Dimethylhexane is moderately toxic.

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.
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]
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]
