New carbonate polyethers carrying cyclic carbonate groups, extractant organic composition based on these compounds and process for extracting metal values from these compositions |
摘要 |
New carbonate polyethers carrying cyclic carbonate groups of general formula: <IMAGE> in which: R1 is a hydrocarbon group containing 2 to 10 carbon atoms, substituted by at least one chain <IMAGE> R2 or R3, which are identical or different, are linear or branched alkyl groups containing 2 to 20 carbon atoms or aromatic groups optionally substituted by one or a number of lower alkyl radicals, n and p are independently of each other between 0 and 40 but are not both zero simultaneously. These new carbonate polyethers, dissolved in an aromatic solvent, form organic solutions which extract many metal values.
