Hydrogenation, Fermentation, and Polymerization: Chemical Processes
Hydrogenation
Hydrogenation is a type of chemical reaction (redox) in which the visible end result is the addition of hydrogen (H2) to another compound. The usual targets of this reaction are unsaturated organic compounds such as alkenes, alkynes, ketones, nitriles, and amines. Most hydrogen is produced by direct addition of diatomic hydrogen under pressure and in the presence of a catalyst.
A typical example of hydrogenation is the addition of hydrogen to double bonds, converting alkenes to alkanes.
