Hydrogenation - Wikipedia
Hydrogenation is a chemical reaction between molecular hydrogen (H 2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds.
Hydrogenation: Definition, Examples, and Applications
Hydrogenation is an essential chemical reaction for the synthesis of new chemicals. The reaction occurs between a hydrogen molecule and an unsaturated compound, like alkene and alkyne, in the presence of a metal catalyst.
Hydrogenation | Catalytic, Hydrophobic & Lipids | Britannica
hydrogenation, chemical reaction between molecular hydrogen and an element or compound, ordinarily in the presence of a catalyst. The reaction may be one in which hydrogen simply adds to a double or triple bond connecting two atoms in the structure of the molecule or one in which the addition of hydrogen results in dissociation (breaking up) of ...
What Is Hydrogenation? Chemistry Definition - ThoughtCo
2019年12月3日 · Hydrogenation is a chemical reaction that adds hydrogen to a molecule. Hydrogenation is not thermodynamically favorable at ordinary temperatures, so a catalyst is needed. Usually this catalyst is a metal. Examples of hydrogenated products include margarine, mineral turpentine, and aniline.
Catalytic Hydrogenation of Alkenes - Chemistry LibreTexts
2023年1月23日 · An example of an alkene addition reaction is a process called hydrogenation.In a hydrogenation reaction, two hydrogen atoms are added across the double bond of an alkene, resulting in a saturated alkane. Hydrogenation of a double bond is a thermodynamically favorable reaction because it forms a more stable (lower energy) product.
Hydrogenation - an overview | ScienceDirect Topics
Hydrogenation is the chemical treatment of plastic waste with hydrogen in the presence of a suitable catalyst. Compared to other methods, hydrogenation forms highly saturated products, without olefins in the oil because of which we can use the fuel without any further treatment.

An example of an alkene addition reaction is a process called hydrogenation. In a hydrogenation reaction, two hydrogen atoms are added across the double bond of an alkene, resulting in a saturated alkane. Hydrogenation of a double bond is a thermodynamically favorable reaction because it forms a more stable (lower energy) product.
11.2: Hydrogenation with Heterogeneous Catalysts
2021年7月31日 · Mechanism of Hydrogenation; Catalyst Activity and Selectivity; Contributors and Attributions; Addition of hydrogen to a multiple bond is hydrogenation. It is applicable to almost all types of multiple bonds and is of great importance in synthetic chemistry, particularly in the chemical industry.
Hydrogenation - Organic Chemistry - Socratic
Hydrogenation is the process of using a hydrogen molecule (H₂) with a catalyst to saturate an organic compound. This process will reduce double and triple bonded carbons and yield hydrocarbons.
Hydrogenation - an overview | ScienceDirect Topics
Hydrogenation is a fundamental process in organic chemistry and has been used for centuries to add elemental hydrogen across unsaturated bonds.
