METHOD OF PALLADIUM ACETATE PRODUCTION Russian patent published in 2009 - IPC C07C53/10 C07F15/00 C07C51/41 C01G55/00 

FIELD: chemistry.

SUBSTANCE: invention refers to platinum metal salts synthesis, specifically palladium salts, namely palladium (II) acetate applied as catalyst or for production of initial salt for other palladium salts. Method of palladium acetate production includes as follows. Metal palladium is dissolved in concentrated nitric acid. Prepared solution is steamed prior to crystallisation of palladium nitrate salt, processed by ice acetic acid. Deposition is filtered and processed with ice acetic acid. Nitrate palladium solution is processed with ice acetic acid with sodium acetate additive in amount 1.5 - 2 kg per 1 kg of palladium in solution. Deposition is processed and dissolved in ice acetic acid in ratio 19-21 l per 1 kg of deposition with acetamide added in amount 0.1 - 0.2 kg per 1 kg of deposition. Solution is warmed at temperature 80 - 90 °C within at least 5 h and steams until salt is formed.

EFFECT: simplification of monophase palladium (II) acetate production with decreased adverse environmental effects of process products.
