摘要： A process for selective liquid-liquid extraction of germanium from an aqueous acidic liquor containing, besides germanium, at least one other metal selected from the group which comprises cadmium, zinc, cobalt, iron, arsenic and nickel. This process includes extracting germanium from said aqueous liquor by contacting said liquor with an organic medium containing a diluent and an extractant, said diluent being immiscible with said aqueous liquor. The major part of germanium passes from said aqueous liquor to an organic phase which is subsequently submitted to a stripping step by contacting with an alkaline medium, with formation of an aqueous phase containing the major part of germanium from said aqueous liquor.

摘要： It has been discovered that relatively large cyclic and open chain carbonates are extremely efficient in the selective extraction of metal ions, such as gold, silver, platinum and mercury from aqueous solution without the need for a potentially hazardous, organic solvent or use of a corrosive salt, such as NaCl. For example, 1,2-decane carbonate extracted >99.9% mercury, 99.76% gold, 97.5% silver and 79.0% platinum. The homologous 1,2-dodecane carbonate was found to extract 99.9% gold and silver from aqueous solution and 95.8% platinum. Didecyl carbonate extracted 77% gold from aqueous solution. The method of this invention is simpler than prior techniques and eliminates the need for potentially hazardous solvents (toxic, flammable and environmentally unfavorable) and corrosive additives, such as salt, NaCl, used as a salting agent in prior methods.

摘要： Macrocyclic oxamides may be made easily, in good yield and in one step by reacting an oxalic compound, such as oxalic acid or oxalic esters, with a diamine, where the amine groups are separated by at least five atoms. The oxalic compounds may include, but are not limited to such materials as dimethyl oxalate and diethyl oxalate. The diamines may include, but are not limited to such materials as alkylenediamines; polyalkylene glycol diamines; alkyl-bis-(aminoalkyl)amines; imino bis-(alkyl)amines; and N,N' bis-(aminoalkyl)-N,N'-dialkylalkylenediamines and bis-(aminoalkyl)piperazines; and mixtures thereof. The macrocyclic oxamides made by this process may be used to selectively separate metal ions from solution, or complexed together with a metal ion act as a catalyst.
