The Evelyn effect is defined as the phenomena in which the product ratios in a chemical reaction change as the reaction proceeds. This phenomenon contradicts the fundamental principle in organic chemistry by reactions always go by the lowest energy pathway. The favored product should remain so throughout a reaction run at constant conditions.
Cyclohexanol is the organic compound with the formula HOCH(CH 2) 5. The molecule is related to cyclohexane by replacement of one hydrogen atom by a hydroxyl group . [ 4 ] This compound exists as a deliquescent colorless solid with a camphor-like odor, which, when very pure, melts near room temperature.
It can be produced by a Wittig reaction or a reaction with a Tebbe's reagent from cyclohexanone. [1] [2] [3] It can also be synthesized as a side product of the dehydration of 2-methylcyclohexanol into 1-methylcyclohexene.
4-Methylcyclohexanemethanol (MCHM, systematic name 4-methylcyclohexylmethanol) is an organic compound with the formula CH 3 C 6 H 10 CH 2 OH. Classified as a saturated higher alicyclic primary alcohol. Both cis and trans isomers exist, depending on the relative positions of the methyl (CH 3) and hydroxymethyl (CH 2 OH) groups on the cyclohexane ...
Methylcyclohexanones are a group of three isomers: 2-methylcyclohexanone, 3-methylcyclohexanone, and 4-methylcyclohexanone. [1] They can be viewed as derivative of cyclohexanone. They can be prepared by oxidation of methylcyclohexane as well as partial hydrogenation of the corresponding cresols. All are colorless liquids.
Cyclohexane-1,2,3,4,5,6-hexol is a family of chemical compounds with formula C 6 H 12 O 6, whose molecule consists of a ring of six carbon atoms, each bound to one hydrogen atom and one hydroxyl group (–OH). There are nine stereoisomers, that differ by the position of the hydroxyl groups relative to the mean plane of the ring.
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 ...
The conversion of ethanol to ethylene is a fundamental example: [3] [4] CH 3 CH 2 OH → H 2 C=CH 2 + H 2 O. The reaction is accelerated by acid catalysts such as sulfuric acid and certain zeolites. These reactions often proceed via carbocation intermediates as shown for the dehydration of cyclohexanol. [5] Some alcohols are prone to dehydration.
