摘要:

AbstractThe distribution ratios of two isomeric 5, 7, 7, 12, 12, 14‐hexamethyl‐1, 4, 8, 11‐tetraazacyclotetradecane, tetcand tetd, in several solvent systems at 25.0°Cas functions of hydrogen ion concentration were determined. The protonation constants and the distribution constants of these macrocyclic ligands and their protonated species were obtained from the variations of the distribution ratios in the range of 6<–log
