Ethenone is produced by thermal dehydration of acetic acid at 700–750 °C in the presence of triethyl phosphate as a catalyst: [7] [8] CH 3 CO 2 H → CH 2 =C=O + H 2 O. It has also been produced on a laboratory scale by the thermolysis of acetone at 600–700 °C. [9] [10] CH 3 COCH 3 →CH 2 =C=O + CH 4. This reaction is called the ...
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.
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).

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 :
140.226 g·mol −1 Density: 0.905 g/cm 3: Boiling point: 198 to 200 °C (388 to 392 °F; 471 to 473 K) ... [1] Another cyclohexylacetone use is in the production of ...
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.
The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
Cyclohexylmethanol is an organic compound with the formula C 6 H 11 −CH 2 −OH. It is a cyclohexane ring functionalized with an alcohol , specifically a hydroxymethyl group. The compound is a colorless liquid, although commercial samples can appear yellow.
