✦ Synopsis
The & vs. composition relationships of several solutes containing two or three functional groups (hydroxyl, amino and nitro groups), chromatographed in the system chloroform f electron-donor solvent-water, were compared with analogous plots obtained using simpler systems: cyclohexane i-chloroform-water and cyclohexane + electron-donor solvent-water. For systems with tributyl phosphate as the donor solvent, the extraction strengths of the binary mixed solvent are significantly lower than estimated from the additivity principle. The discrepancies were different for different solutes.
