N2 - Cell Assembly for the Potentiometric Determinatin of the Enantiomeric Excess of 1‐Phenylethylammonium‐Ions A cell assembly with two membranes containing each one enantiomer of the ionophor N,N,N′,N′,N″,N″,N‴,N‴‐octabutyl‐1,4,7,10,16‐hexaoxacyclooctadecane‐2,3,11,12‐tetracarboxamide is used for the direct potentiomewtirc determination of the enantiomeric excess ee of 1‐phenylethylammonium ions in aqueous solutions. The preference for the (R)‐over the (S)‐1‐phenylethylammonium ion by the (2R,3R,11R,12R)‐ionophor of 2.7 allows a reliable determination of ee even in the presence of known concentrations of the heavy interferent KCl.
