PRONUNȚIA HYDROGENATE ÎN ENGLEZĂ

hydrogenate  [ˈhaɪdrədʒɪˌneɪt]

CE ÎNSEAMNĂ HYDROGENATE ÎN ENGLEZĂ?

Hidrogenarea

Hydrogenation

Hidrogenarea - pentru a trata cu hidrogen - este o reacție chimică între hidrogenul molecular și un alt compus sau element, de obicei în prezența unui catalizator cum ar fi nichel, paladiu sau platină. Procesul este utilizat în mod obișnuit pentru reducerea sau saturarea compușilor organici. Hidrogenarea reprezintă de obicei adăugarea de perechi de atomi de hidrogen la o moleculă, în general o alchenă. Catalizatorii sunt necesari pentru ca reacția să fie utilizabilă; hidrogenarea ne-catalitică are loc numai la temperaturi foarte ridicate. Hidrogenarea reduce legăturile duble și triple în hidrocarburi. Din cauza importanței hidrogenului, au fost dezvoltate multe reacții înrudite pentru utilizarea sa. Cele mai multe hidrogenări utilizează hidrogen gazos, dar unele implică sursele alternative de hidrogen, nu H2: aceste procese se numesc hidrogenări de transfer. Reacția inversă, îndepărtarea hidrogenului dintr-o moleculă, se numește dehidrogenare. O reacție în care legăturile sunt rupte în timp ce se adaugă hidrogen se numește hidrogenoliză, o reacție care poate apărea la legăturile carbon-carbon și carbon-heteroatom.

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.
