[Benzylpenicillin interaction with amines in the organic phase].
Benzylpenicillin interaction with amines in the nonaqueous phase was studied by pH dependence of the coefficient of the antibiotic distribution in the system of amine butyl acetate solution--water. A distribution scheme involving interaction of the amine molecular and cationic forms with benzylpenicillin and amine dissociation equilibrium in organic solution is described. On the basis of the experimental data the interaction and dissociation constants were determined for a number of aromatic and aliphatic amines.
