Catalytic Hydrogenation of Ethylene
C2H4 + H2 → C2H6
Visão geral
Ethylene is reduced to ethane by addition of hydrogen across the double bond, catalyzed by a transition metal surface. Both hydrogen atoms add to the same face of the alkene (syn addition). The metal catalyst adsorbs both H₂ and the alkene, weakening bonds and facilitating the reaction.

Exemplo do cotidiano
Margarine is made by partial hydrogenation of vegetable oils, converting liquid unsaturated fats to solid saturated fats.
Importância industrial
A hidrogenação catalítica é utilizada no refino de petróleo, produção de margarina, fabrico farmacêutico e síntese química fina. Paul Sabatier ganhou o Prémio Nobel de 1912 por este trabalho.
