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 .

Catalytic Hydrogenation of Alkenes - Chemistry LibreTexts

Introduction. 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.

Difference Between Hydrogenation and Hydrogenolysis .

Hydrogenation is a chemical reaction that occurs between molecular hydrogen (H 2) . cleavage of benzyl ethers. However, the operation of hydrogenolysis in the laboratory is somewhat similar to hydrogenation. This reaction is widely used in petrochemical industry. It is used to remove sulfur from feedstock in petroleum refineries.
