The appearance of palladium is black powdery particles with a melting point of 1555 ° C and a boiling point of 3167 ° C. It is soluble in water.
Palladium is widely used in the hydrorefining and refining process of petrochemical, pharmaceutical, electronics, perfumery, dyestuff and other fine chemicals.
Palladium carbon is a catalyst prepared by supporting metal palladium powder on activated carbon, and its main function is catalytic hydrogenation of unsaturated hydrocarbons or CO. It has the characteristics of high hydrogenation reductibility, good selectivity, stable performance, low feed ratio when used, repeated application, and easy recovery.
Palladium carbon mainly used in catalysts (palladium asbestos, sponge palladium, etc.), low current contact points, printed circuits, alloys for watches, etc.
Palladium carbon is dissolved in ethanol under vacuum and pumped into autoclave or poured into autoclave. Then, the vessel is washed with ethanol and then put into the kettle. After the reaction, the material is recovered by palladium carbon through the filter. The reaction vessel can be washed with reaction solvent and palladium is recovered through the filter.
