QUE SIGNIFIE HYDROGENATE EN ANGLAIS

Hydrogénation

Hydrogenation

L'hydrogénation - à traiter avec de l'hydrogène - est une réaction chimique entre l'hydrogène moléculaire et un autre composé ou élément, habituellement en présence d'un catalyseur tel que le nickel, le palladium ou le platine. Le procédé est couramment utilisé pour réduire ou saturer les composés organiques. L'hydrogénation constitue typiquement l'addition de paires d'atomes d'hydrogène à une molécule, généralement un alcène. Les catalyseurs sont nécessaires pour que la réaction soit utilisable; L'hydrogénation non catalytique n'a lieu qu'à des températures très élevées. L'hydrogénation réduit les liaisons doubles et triples dans les hydrocarbures. En raison de l'importance de l'hydrogène, de nombreuses réactions connexes ont été développées pour son utilisation. La plupart des hydrogénations utilisent de l'hydrogène gazeux, mais certaines impliquent les sources d'hydrogène alternatives, et non H2: ces procédés sont appelés hydrogénations de transfert. La réaction inverse, l'élimination de l'hydrogène d'une molécule, s'appelle la déshydrogénation. Une réaction où les liaisons sont interrompues alors que de l'hydrogène est ajouté est appelée hydrogénolyse, une réaction qui peut se produire aux liaisons carbone-carbone et hétéroatome carbone.

Hydrogenation – to treat with hydrogen – is a chemical reaction between molecular hydrogen 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, generally an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces 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, 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 bonds.
