Abstract

1,126,200. Extracting palladium values. BADISCHE ANILIN- & SODA-FABRIK A.G. 24 Dec., 1965 [28 Dec., 1964], No. 54779/65. Heading C1A. Palladium values are extracted from an aqueous solution containing them by a method of liquid/liquid extraction using an amine which contains at least six carbon atoms per nitrogen atom, or solution of such amine in an organic solvent, separating the amine phase and reextracting the Pd values with an aqueous acid solution, the amount and/or the concentration of the aqueous acid being greater than in the original solution so that the activity of PO<SP>2+</SP> in said aqueous acid is less than in the original solution. The inert solvent for the amine preferably has little or no miscibility with water. The original aqueous solution may be acid and may have been obtained in the process for the production of glyoxal by oxidizing ethylene in which Pd is a catalyst. Suitable aqueous acids for the re-extraction are given as HC1, H 2 SO 4 , H 3 PO 4 and HNO 3 , but palladium iodide, bromide, chloride, sulphate and nitrate are recorded as being obtained by the process, although nitric acid is the preferred acid and the obtaining of solutions of Pd in nitric acid is exemplified. Lists of suitable amines and inert solvents are given in the Specification.
