Summary: The paper explains the theoretical aspects of the process of enantiomerization and describes its characteristic
features (generation of a plateau). In addition, some complications are presented that are produced by
enantiomerization either from analytical or pharmacological points of view. It also defines the way of how to
calculate energy barriers of enantiomerization according to the methods used for the separation of racemic
mixtures (stopped-flow or dynamic chromatography). Mathematic models useful in deconvolution of
chromatograms are also described. With the use of dynamic methods it is not possible to quantitatively evaluate
the obtained chtromatograms and calculate thermodynamic parameters without computer-assisted
deconvolution.
