    • Novel complexes of macrocyclic polyethers such as 1,4,7,10,13,16-hexaoxacyclooctadecane (18-crown-6) and disulfonates of the formula I ##STR1## wherein X represents barium or strontium and R.sup.1 is an alkylene moiety, optionally substituted with an alkyl group, are described as well as a process for isolating said macrocylic polyethers through formation of said novel complexes. In the isolation process disclosed, a macrocyclic polyether containing solution is contacted with a disulfonate of formula I to afford the polyether-disulfonate complex as a solid suspension in the solution, the suspended complex is separated from the solution and the separated complex is extracted with a solvent for the macrocyclic polyether.
    • 大环聚醚如1,4,7,10,13,16-六氧杂环十八烷(18-冠-6)和式I的二磺酸盐的新型配合物,其中X表示钡或锶,R 1是亚烷基部分, 描述了任选被烷基取代的方法,以及通过形成所述新型配合物分离所述大环聚醚的方法。 在所公开的分离方法中,将含大环聚醚的溶液与式I的二磺酸酯接触,得到溶液中固体悬浮液的聚醚 - 二磺酸盐络合物,将悬浮的络合物与溶液分离,并将分离的络合物用 溶剂用于大环聚醚。
