Abstract

We report data concerning the association of monovalent cations with some polyethyleneglycol ethers that we have prepared. 1: 1 association constants KA have been obtained in methyl alcohol at 25° C using selective glass electrode potentiometric measurements for Na+ and K+ and conductimetric measure ments for Cs+ and Tl+. The values obtained for KA and for the selectivity ratio KA (K+)/KA (Na+) increase with the ...
