Ionized organic compounds can be extracted into organic phases as ion-pairs with counter ions of suitable hydrophobic character. The distribution ratio depends on the structure of the ion-pair and the concentration of the counter ion. Systems for liq

Selective and easily regulated systems for extraction of organic compounds as ion-pairs and/or adducts are presented. The effect of different kinds of hydrophobic agents that give adducts in the organic phase are demonstrated: mesitylene for nitrophe

Conditions for determination of quaternary ammonium compounds and amines by two-phase titration have been calculated on the basis of extraction constants for the ion-pairs between the titrant (lauryl sulphate), the indicator (Methyl Yellow) and the s
