- 中文摘要: The distribution ratios of two isomeric 5,7,7,12,12,14-hexamethyl-1,4,8,11-tetraazacycloteradecane, tet c and tet d, in several solvent systems at 25.0℃ as function 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 rations in the range of 6<-log [H+] <14.
