ABSTRACT:
The invention relates to substituted derivatives of per(3,6-anhydro)cyclodextrins, their preparation process and their use for the separation of ions.
These derivatives comply with one of the formulas: ##STR1## in which the R.sup.1, which can be the same or different, represent H, a halogen, OH, OR.sub.2, OM, SH, SR.sup.2, OCOR.sup.2, NH.sub.2, NR.sup.2 R.sup.3, CONR.sup.2 R.sup.3, CONH.sub.2, CN, COOR.sup.2, COOH, OSO.sub.2 R.sup.2, N.sub.3 or R.sup.2, and n=5, 6 or 7, provided that all the R.sup.1 do not represent OH.
