METHOD FOR OBTAINING PALLADIUM ACETATE Russian patent published in 2008 - IPC C07C53/10 C07F15/00 C07C51/41 C01G55/00 

FIELD: chemistry.

SUBSTANCE: invention concerns platinum-group metal salt synthesis, particularly of palladium salts, namely palladium (II) acetate applied as catalyst or for obtaining basic salt to produce other palladium salts. The method for obtaining palladium acetate involves dissolution of metal palladium in concentrated nitric acid, evaporation of obtained solution and reaction with acetic acid, where, after evaporation but prior to palladium (II) nitrate crystallisation, the palladium nitrate solution is processed by a mix of acetic acid, acetic acid ethyl alcohol and acetic anhydride at (60-80)°C with (2.0-3.0) l of ice-cold acetic acid, (0.8-1.0) l of ethylacetate and (0.4-0.6) l of acetic anhydride per 1 kg of dissolved palladium for at least 1 hour, the resulting solution is heated at (90-110)°C for at least 3 hours and at (135-145)°C for at least 6 hours.

EFFECT: obtaining high yield of monophase palladium (II) acetate without admixture of insoluble polymeric palladium (II) acetate and palladium (II) nitritoacetate.
