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 for production of other palladium salts. The method for obtaining palladium acetate involves dissolution of metal palladium in concentrated nitric acid, filtration and evaporation of palladium nitrate solution and reaction with acetic acid, where after evaporation but prior to palladium (II) nitrate crystallisation the palladium nitrate solution is processed by distilled water in the volume of (2-5) l per 1 kg of palladium in the initial nitrate solution, then by acetic acid diluted with water, with acid concentration of (30-70)% and volume of (1.5-2.5) l of acetic acid per 1 kg of palladium in the initial nitrate solution, the resulting solution being matured for at least 8 hours at (15-40)°C.

EFFECT: streamlined method for obtaining palladium (II) acetate and its synthesis in monophase condition without admixture of insoluble polymeric palladium (II) acetate and palladium (II) nitritoacetate.
