ABSTRACT:
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.
