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.
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.
Ethenone is a highly reactive gas (at standard conditions) and has a sharp irritating odour.It is only reasonably stable at low temperatures (−80 °C). It must therefore always be prepared for each use and processed immediately, otherwise a dimerization to diketene occurs or it reacts to polymers that are difficult to handle.
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 . The oxidation involves radicals and the intermediacy of the hydroperoxide C 6 H 11 O 2 H. Alternatively, cyclohexanol can be produced by the hydrogenation of phenol :
For gases, departure from 3 R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to ...

The density is 882.73 kgm −1. The isothermal compressibility is 674 TPa −1 and isobaric expansivity is 819 K −1. [5] When bicyclohexyl is heated to around 427 °C (801 °F) it slowly decomposes to cyclohexane and cyclohexene, as the pivot bond joining the two rings is the longest and weakest one. [6] Heat of combustion is 1814.8 kcal/mol. [7]
