Dehydrogenation - Wikipedia
In chemistry, dehydrogenation is a chemical reaction that involves the removal of hydrogen, usually from an organic molecule. It is the reverse of hydrogenation. Dehydrogenation is important, both as a useful reaction and a serious problem.
15.5: Hydrogenation of alkenes and Dehydrogenation of Alkanes
Jul 20, 2022 · We turn next to reactions in which a hydrogen molecule is added to the double bond of an alkene, forming an alkane - and the reverse, in which H2 H 2 is eliminated from an alkane to form an alkene. Many biochemical reactions of this type involve α α, β β …
Dehydrogenation (Dehydration) of Alcohols - BYJU'S
Alcohol upon reaction with protic acids tends to lose a molecule of water to form alkenes. These reactions are known as dehydrogenation or dehydration of alcohols. It is an example of an elimination reaction. Its rate varies for primary, secondary and tertiary alcohols.
Dehydrogenation - an overview | ScienceDirect Topics
Dehydrogenation is the process by which hydrogen is removed from an organic compound to form a new chemical (e.g., to convert saturated into unsaturated compounds). It is used to produce aldehydes and ketones by the dehydrogenation of alcohols.
Dehydrogenation | chemical reaction | Britannica
elimination reaction, any of a class of organic chemical reactions in which a pair of atoms or groups of atoms are removed from a molecule, usually through the action of acids, bases, or metals and, in some cases, by heating to a high temperature.
Dehydrogenation - an overview | ScienceDirect Topics
Dehydrogenation is a chemical reaction that involves the elimination of hydrogen (H2) and is the reverse of hydrogenation (Speight and Ozum, 2002; Speight, 2007). Dehydrogenation reactions are of major industrial importance, especially in the production of constituents for the manufacture of high-octane gasoline.
Reversible dehydrogenation and rehydrogenation of ... - Nature
Mar 1, 2022 · Developing highly efficient and reversible hydrogenation-dehydrogenation catalysts shows great promise for hydrogen storage technologies with highly desirable economic and ecological benefits.
Selective dehydrogenation of small and large molecules by a ...
Sep 23, 2022 · The dehydrogenation of abundant alkane feedstocks to olefins is one of the mostly intensively investigated reactions in organic catalysis. A long-standing, pervasive challenge in this transformation is the direct dehydrogenation of unactivated 1,1-disubstituted ethane, an aliphatic motif commonly found in organic molecules.
Formic acid dehydrogenation using Ruthenium-POP pincer
Oct 31, 2024 · Published catalytic systems for formic acid dehydrogenation, however, typically require the use of volatile organic solvents, water, or neat formic acid 11,12,13,14, potentially leading to the ...
Applications of Acceptorless Dehydrogenation and Related ...
In acceptorless dehydrogenation (AD) reactions, catalytic scission of C−H, N−H, and/or O−H bonds liberates hydrogen gas with no need for a stoichiometric oxidant, thereby providing efficient, nonpolluting activation of substrates. In addition, the hydrogen gas is valuable in itself as a high-energy, clean fuel.
