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 ...
1,4-Cyclohexadiene is an organic compound with the formula C 6 H 8. It is a colourless, flammable liquid that is of academic interest as a prototype of a large class of related compounds called terpenoids, an example being γ-terpinene. An isomer of this compound is 1,3-cyclohexadiene.
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]
The resulting aminopolycarboxylic acid, upon ionization of the carboxylic acid groups, is a high affinity chelating agent for di- and trivalent cations. The tetracarboxylic acid was first reported in 1976. [2] At the time of its discovery DOTA exhibited the largest known formation constant for the complexation of Ca 2+ and Gd 3+ ions. Modified ...
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.
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. The compound is a colorless liquid, although commercial samples can appear yellow.
In organic chemistry, a variety of synthetic procedures are particularly useful in closing carbocyclic and other rings; these are termed ring-closing reactions. Examples include: alkyne trimerisation; the Bergman cyclization of an enediyne; the Diels–Alder, between a conjugated diene and a substituted alkene, and other cycloaddition reactions;
1,4-Cyclohexanedimethanol diglycidyl ether is an organic chemical in the glycidyl ether family. [2] Its formula is C 14 H 24 O 4 and the IUPAC name is 2-[[4-(oxiran-2-ylmethoxymethyl)cyclohexyl]methoxymethyl]oxirane. It has the CAS number of 14228-73-0 [3] and is REACH registered in Europe. [4]
