METHOD OF OBTAINING PALLADIUM ACETATE Russian patent published in 2010 - IPC C07C53/10 C07F15/00 C07C51/41 C01G55/00 

FIELD: chemistry.

SUBSTANCE: method of obtaining palladium acetate involves dissolving palladium metal in concentrated nitric acid, evaporation of the obtained solution and reaction with acetic acid, where the palladium nitrate solution after evaporation, before crystallisation of palladium (II) nitrate salt, is treated with nitrogen (II) oxide or a mixture of nitrogen (II) and (IV) oxides containing not more than 30% nitrogen (IV) oxide and acetic acid at temperature of the solution of 40-90°C with glacial acetic acid consumption of 1.5-2.5 l per kg of palladium in the solution and nitrogen (II) oxide or mixture of nitrogen (II) and (IV) oxides consumption of 1.0-2.0 m³ at normal conditions per 1 l of the initial palladium nitrate solution for 0.5-1.5 hours and the formed solution is heated in a nitrogen atmosphere at 110-140°C for not less than 2 hours with consumption of elementary nitrogen of approximately 30 m³ per 1 m³ of the formed solution.

EFFECT: obtaining palladium acetate in monophase state and avoding formation of impurities of insoluble palladium catena-poly-acetate.
