Hydrogenation - to treat with hydrogen - is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, generally an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogen adds to double and triple bonds in hydrocarbons.
Because of the importance of hydrogen, many related reactions have been developed for its use. Most hydrogenations use gaseous hydrogen (H2), but some involve the alternative sources of hydrogen, not H2: these processes are called transfer hydrogenations. The reverse reaction, removal of hydrogen from a molecule, is called dehydrogenation. A reaction where bonds are broken while hydrogen is added is called hydrogenolysis, a reaction that may occur to carbon-carbon and carbon-heteroatom (oxygen, nitrogen or halogen) bonds. Hydrogenation differs from protonation or hydride addition: in hydrogenation, the products have the same charge as the reactants.
An illustrative example of a hydrogenation reaction is the addition of hydrogen to maleic acid to form succinic acid. Numerous important applications of this petrochemical are found in pharmaceutical and food industries. Hydrogenation of unsaturated fats produces saturated fats and, in some cases, trans fats.

When liquid oils are turned into solid fats through a process?
This process is called hydrogenation.
Does Hydrogenation increase a fat's susceptibility to rancidity and shortens its shelf life?
Yes, hydrogenation of fat does increase its shelf life. The hydrogenation of the unsaturated fats usually produces the saturated fats.
Is margarine made from plastic?
No. It is made by the hydrogenation of oils or fats.
What has the author H B W Patterson written?
H. B. W. Patterson has written: 'Hydrogenation of fats and oils' -- subject(s): Analysis, Edible Oils and fats, Hydrogenation, Oils and fats, Oils and fats, Edible 'Bleaching and purifying fats and oils' -- subject(s): Oils and fats, Bleaching, Purification
Unsaturated fats may be turned into saturated fats by a process called?
hydrogenation for Plato the answe is C :P
If Trans fats are inadvertently formed during the hydrogenation of vegetable oils is the hydrogenation of oils an oxidation or reduction reaction?
The parital hydrogenation of oils and fats reduces the cis double bonds in fats to give them a more solid form at room temperature. As the reduction process takes place at high temperatures, there is thermal isomerization of some of the cis bonds to their trans form.
Hydrogenation of vegetable oil means that the final product is what?
high in polyunsaturated fats
What process is used to convert polyunsaturated oils into saturated fats?
olive and canola oils are examples of saturated fats
What is it called When hydrogen has been added to unsaturated fats?
The chemical process in which hydrogen atoms are added to unsaturated and polyunsaturated fats is hydrogenation.
What is the process used to turn liquid oils into more highly saturated solid fats?
Hydrogenation .
Which is the gas that is used for converting vegetable oils into saturated fats?
Hydrogen. The process is called hydrogenation.
What process is used to turn liquid oils into more highly saturated solid fats?
This process is hydrogenation.
