Application

Palladium on barium sulfate (Pd/BaSO4), also known as Rosenmund catalyst, is used for the decarboxylation of aliphatic esters for further production of biodiesel. It can also be used in hydrogenation reaction. Pd/BaSO4 may be used as a catalyst reservoir for the Stille cross-coupling reaction between iodobenzene and tributylphenyltin.
