METHOD OF PRODUCING PALLADIUM TRIFLUOROACETATE

摘要

FIELD: chemistry.SUBSTANCE: method includes dissolving palladium metal in concentrated nitric acid and evaporating the obtained solution. The palladium nitrate solution is evaporated at (40-80)°C until palladium nitrate begins to crystallise. The formed solution at (30-80)°C is mixed with trifluoroacetic acid in amount of (600-800)% of the molar amount of palladium in the starting palladium nitrate solution or trifluoroacetic acid anhydride in amount of (350-450)% of the molar amount of palladium in the starting palladium nitrate solution until the end of crystallisation of polymeric palladium trifluoroacetate. The method also includes filtering the formed compound and conversion thereof into the end product by adding acetonitrile at (10-30)°C with weight ratio of the compound to acetonitrile of 1:(0.5-2).EFFECT: invention improves the method of producing palladium trifluoroacetate in a crystalline monophase state, improves synthesis stability and enables to achieve high output of the desired compound.2 cl, 2 tbl, 2 ex
