[Equilibrium distribution of weak electrolytes in an organic solvent-water system].

Distribution of cephalotin, 2-tienylacetic acid, phenacetyl-D-(--)-alpha-aminophenylacetic acid, weak acids and D-(--)-alpha-amino-phenylacetic acid methyl ether, a weak base in two-phase systems containing two immiscible liquid phases was studied. The constants of the intraphase and interphase equilibrium necessary for complete quantitative description of the system of electrolyte aqueous solution-organic solvent were determined.
