Oxidative dehydrogenation (ODH) of n-butane is an alternative to classical dehydrogenation, steam cracking and fluid catalytic cracking processes. [5] [6] Formaldehyde is produced industrially by oxidative dehydrogenation of methanol. This reaction can also be viewed as a dehydrogenation using O 2 as the acceptor.
Soluble transition metal complexes can induce oxidative aromatization concomitant with complexation. α-Phellandrene (2-methyl-5-iso-propyl-1,3-cyclohexadiene) is oxidised to p-iso-propyltoluene with the reduction of ruthenium trichloride. [11] Oxidative dehydrogenation of dihydropyridine results in aromatization, giving pyridine. [12]
This oxidant is useful for the dehydrogenation of alcohols, [3] phenols, [4] and steroid ketones. [5] DDQ decomposes in water, but is stable in aqueous mineral acid. [6]
One of the most common examples of carbocatalysis is the oxidative dehydrogenation of ethylbenzene to styrene discovered in the 1970s. [1] Also in the industrial process of (non-oxidative) dehydrogenation of ethylbenzene, the potassium -promoted iron oxide catalyst is coated with a carbon layer as the active phase.
These enzymes are O 2-dependent, consistent with their function as either hydroxylation or oxidative dehydrogenation. [3] Desaturases produce unsaturated fatty acids. Unsaturated fatty acids help maintain structure and function of membranes. Highly unsaturated fatty acids are incorporated into phospholipids and participate in cell signaling. [4]
An aqueous solution of the rhodium catalyst converts the propylene to the aldehyde, which forms a lighter (less dense) immiscible phase. About 6 billion kilograms are produced annually in this manner. Butyraldehyde can be produced by the catalytic dehydrogenation of n-butanol.
Oxidative decarboxylation is a decarboxylation reaction caused by oxidation. Most are accompanied by α- Ketoglutarate α- Decarboxylation caused by dehydrogenation of hydroxyl carboxylic acids such as carbonyl carboxylic malic acid , isocitric acid , etc. [ 1 ]
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols.
