钯,5%负载于碳酸钙

Palladium (5%) on calcium carbonate powder (reduced) is a heterogeneous and a mild catalyst, used in the hydrogenation of aromatic and aliphatic nitro groups, reductive alkylation/amination, hydrogenation of aromatic carbonyls, olefins, and nitriles. It has high selectivity towards certain chemical reactants, and is often the preferred heterogeneous catalyst for a wide variety of chemical reactions. Partially deactivated form of palladiuim (5%) on calcium carbonate is known as Lindlar catalyst, which is useful for chemo and stereoselective hydrogenations, such as alkynes to cis-alkenes (for e.g., Vitamin synthesis).

Incompatible with materials like strong oxidizing agents and arsenic.
