4 Calix[4]arene-crown-5 as a selective extraction reagents for K /H , Rb /H and Rb /Cs separations

Popis výsledku v původním jazyce

From extraction experiments, the exchange extraction constants corresponding to the general equilibriums M+ (aq) + NaL+ (org) ⇔ ML+ (org) + Na+ (aq) or M+ (aq) + CsL+ (org) ⇔ ML+ (org) + Cs+ (aq), which take place in the two-phase water–nitrobenzene extraction system (M+ = Li+ , H3O+ , Ag+ , K+ , NH4+, Tl+, Rb+; L = calix[4]arene-bis crown5(1,3- alternate ), 26,28-dipropoxycalix[4]arene-crown-5(1,3- alternate ), 11,23-dibromo-25,28-dipropoxycalix[4]arene-crown-5 (1,3- alternate ) and 1,3- alternate -25,27-dihydroxycalix[4]arene-crown-5; aq = aqueous phase, org = organic phase), were evaluated. The stability constants of the NaL+ and CsL+ complexes were calculated from the extraction of the respective picrates in the system of water–nitrobenzene solution of L. Further, the stability constants of the ML+ complexes in nitrobenzene saturated with water were determined. High selectivities were found in some systems under study.
