摘要：

Stability constants of crown ether complexes with protonated primary amines were determined by the solvent extraction method. Stability constants between protonated amines(AH+) and 18-crown-6(L), log KAHL, were found to be 0.4, 0.15, 0.1,-0.05, and-0.1 for protonated methylamine, ethylamine, propylamine, butylamine, and iso-propylamine at 25.0°C, respectively. © 1985 The Chemical Society of Japan.
