... It is desired to separate the following two compounds: CH3(CH2)3OH and CH3(CH2)3NH2. The two compounds have similar KOW values (around 11) but the second compound is basic. What can be done to separate the two? It is desired to transfer butanol (left compound in #2) from water to an organic phase. W ...

Equilibrium chemistry
Equilibrium chemistry is a concerned with systems in chemical equilibrium. The unifying principle is that the free energy of a system at equilibrium is the minimum possible, so that the slope of the free energy with respect to the reaction coordinate is zero. This principle, applied to mixtures at equilibrium provides a definition of an equilibrium constant. Applications include acid-base, host-guest, metal-complex, solubility, partition, chromatography and redox equilibria.
