DERIVES DE PER(3,6-ANHYDRO) CYCLODEXTRINES, LEUR PREPARATION ET LEUR UTILISATION POUR SEPARER DES IONS
摘要:
The invention concerns per(3,6-anhydro)cyclodextrin derivatives, their preparation and their use for separating polluting ions, for example, for human decontamination. Said derivatives correspond to one of the formulae (I) and (II) wherein one R at least represents the -OCH2COOH group and the other R 's, identical or different, correspond to one of the formulae: OH, OR , SH, SR , OCOR , NH2, NHR , NR R , CONH2, CONHR , CONR R , CN, COOR , COOH and R , wherein: R and R , identical or different, represent a saturated or unsaturated hydrocarbon, aliphatic or aromatic group, capable of comprising one several heteroatoms selected among O, S and N; and n is equal to 6, 7 or 8.
