摘要：
Two-phase potentiometric titration was used to determine partition constants for a series of alpha-aminophosphonates (RO)(2)P(O)(CH2NRR2)-R-1 [R = Alk (C-2-C-5), R-1, R-2 = Me, Et, (CH2)(5)] between water and organic solvents, such as chloroform, carbon tetrachloride, toluene, octane, n-octanol, nitrobenzerie, o-xylene, and cyclohexane. Correlations between the partition constants and the number of carbon atoms in substrate molecules were obtained. Solvent effects on partition constants were discussed, and solution parameters of alpha-aminophosphonates were calculated.
