Hydrogenation | Introduction to Chemistry

Hydrogenation is an exothermic reaction, releasing about 25 kcal/mol in the hydrogenation of vegetable oils and fatty acids. For heterogenous catalysts, the Horiuti-Polanyi mechanism explains how hydrogenation occurs. First, the unsaturated bond binds to the catalyst, followed by H 2 dissociation into atomic hydrogen onto the catalyst. Then one .

Hydrogenation - an overview | ScienceDirect Topics

A schematic of the laboratory reactor set-up used by Mathew (2001) and other relevant information about their experiments are included in Fig. 2. Overall hydrogenation involves two parallel reactions, i.e., (i) hydrogenation of the aromatic ring and (ii) hydrogenation of ketonic group (see Eq. (2)). Thus, formation of cyclohexylethanol can be .

Hydrogenation - Wikipedia

Hydrogenation – meaning, to treat with hydrogen – 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 typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene.
