Hydrogenation

<p>Hydrogenation is a <a href="/facts/Chemical_reaction/GpqWlKrz">chemical reaction</a> between molecular <a href="/facts/Hydrogen/BoYHjl0J">hydrogen</a> (H2) and another compound or element, usually in the presence of a <a href="/facts/Catalyst/LPBS7TQC">catalyst</a> such as <a href="/facts/Nickel/KwMCHYRP">nickel</a>, <a href="/facts/Palladium/AXMwDFxs">palladium</a> or <a href="/facts/Platinum/qJC6lQf7">platinum</a>. The process is commonly employed to <a href="/facts/Redox/Pyd5RVcj">reduce</a> or <a href="/facts/Saturated_and_unsaturated_compounds/tde2C216">saturate</a> <a href="/facts/Organic_compound/gqCNaN45">organic compounds</a>. Hydrogenation typically constitutes the addition of pairs of <a href="/facts/Hydrogen/BoYHjl0J">hydrogen</a> <a href="/facts/Atom/FoQ4kGN5">atoms</a> to a molecule, often an <a href="/facts/Alkene/RtYcS6kU">alkene</a>. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces <a href="/facts/Double_bond/qDemMn0c">double</a> and <a href="/facts/Triple_bond/poDWRayX">triple</a> bonds in <a href="/facts/Hydrocarbon/Dcg95Ju5">hydrocarbons</a>.
