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 Schmidlin ketene synthesis. [11] On a laboratory scale it can be produced by the thermal decomposition of Meldrum's acid at temperatures greater ...
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.
[1] It is produced industrially by the hydrogenation of cyclohexanone in the presence of hydrogen sulfide over a metal sulfide catalyst: C 6 H 10 O + H 2 S + H 2 → C 6 H 11 SH + H 2 O. It is also obtained by the addition of hydrogen sulfide to cyclohexene in the presence of nickel sulfide. [2]
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 ...
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.
Dicyclohexylamine is a secondary amine with the chemical formula HN(C 6 H 11) 2. It is a colorless liquid, although commercial samples can appear yellow. It has a fishy odor, typical for amines. It is sparingly soluble in water. As an amine, it is an organic base and useful precursor to other chemicals. [1]
The reaction conducted in two steps beginning with the conversion of DMT to the diester dimethyl 1,4-cyclohexanedicarboxylate (DMCD): C 6 H 4 (CO 2 CH 3) 2 + 3 H 2 → C 6 H 10 (CO 2 CH 3) 2. In the second step DMCD is further hydrogenated to CHDM: C 6 H 10 (CO 2 CH 3) 2 + 4 H 2 → C 6 H 10 (CH 2 OH) 2 + 2 CH 3 OH. A copper chromite catalyst ...
