In general, a palladium catalyst used for catalytic reduction (Pd black, Pd–C) is powdery, and filtration is required after the reaction. Because the palladium reduction catalyst is flammable and has the danger of ignition due to discharge by friction when put into a reactor, in particular, the dry type Pd–C catalyst must be handled carefully regardless of the amount. ... Though the hydrogenation reaction 1 and hydrogenolysis 2., , and are quite different ...
