Thaum lub sijhawm catalytic hydrogenation ntawm ethene, ethene yog tsim ua ntej uas nyob rau hauv cov kauj ruam tom ntej yog ntxiv rau ethane. Hauv cov tshuaj tiv thaiv no, qhov kub ntawm hydrogenation ntawm thawj π daim ntawv cog lus siab dua qhov thib ob.
Yuav ua li cas ethene tau los ntawm ethyl?
Catalytic hydrogenation ntawm ethyne nyob rau hauv lub xub ntiag ntawm hydrogen gas forms ethene. Lindlar's catalyst yog siv. Lindlar's catalyst yog ib qho palladium catalyst lom nrog cov kab ntawm cov hlau lead thiab quinoline.
Cov tshuaj tiv thaiv twg yog ethane tau los ntawm ethyl?
Tau hloov ethyl mus rau hauv ethane ua hydrogenation ntawm alkene 2 zaug nyob rau hauv lub xub ntiag ntawm ib tug catalyst zoo li Palladium los yog Renny Ni nyob rau hauv chav temp.
Yuav ua li cas cov tshuaj tiv thaiv yog tsim cov ethene?
Kev tsim khoom ntawm Ethene (ethylene)
Cov txheej txheem tawg feem ntau cuam tshuam nrog endothermic equilibrium reactions xws li: C2H 6(g) ⇋ C2H4(g) + H2 (g) ΔH=+138 kJ mol.
hom tshuaj tiv thaiv dab tsi tshwm sim rau ethene thiab ethyl?
Ob qho Ethene thiab Ethyne yog unsaturated hydrocarbons. Cov unsaturated hydrocarbons tau txais cov tshuaj tiv thaiv thaum hydrogen ntxiv rau lawv nyob rau hauv lub xub ntiag ntawm catalysts xws li npib tsib xee los yog palladium thiab tau hloov mus rau hauv saturated hydrocarbons. Qhov no yog hu ua Ntxiv Reaction
