Catalytically highly effective precious metal-carboxylate compounds of Ir, Ru, Rh, Pd and Au
Processes produce catalytically highly effective noble metal carboxylate compounds or their solutions that comprise A) a noble metal carboxylate, wherein the noble metal is selected from the group consisting of ruthenium, platinum, palladium, rhodium and gold, and B) at least one compound selected from the group consisting of oxalic acid, a salt of oxalic acid, a derivative of oxalic acid and a salt of the derivative of oxalic acid. The process digests the noble metal with alkaline earth peroxide to produce a digestion mass and dissolves the digestion mass in a carboxylic acid or a carboxylic acid diluted with a protic solvent to produce a resulting solution, whereby alkaline earth ions are separated off as salt of an oxalic acid or salt of oxalic acid derivatives, and the processes do not include any BaSO4 precipitation and filtration of barium sulphate.
CONVERSION OF CESIUM CARBONATE TO CESIUM OXALATE
Processes for producing a disubstituted oxalate are disclosed. The process includes contacting a cesium salt with one or more alcohols and carbon dioxide (CO.sub.2) under reaction conditions sufficient to produce a composition comprising a disubstituted oxalate.
