Liquid Chromatographic Investigation of Spontaneous Oscillatory In Vitro Chiral Conversion and Spontaneous Oscillatory Condensation of Simple Carboxylic Acids in Aqueous and Nonaqueous Media
Figure 2
Sequence of the densitometrically recorded concentration profiles of 2-phenylpropionic acid after: (a) 0 h (racemic mixture), (b) 22.5 h (S-(+) form), (c) 27.5 h (racemic mixture), (d) 46.5 h (R-(−) form), (e) 51.5 h (shift from R-(−) form to racemic mixture), and (f) 70.5 h (racemic mixture), storage time at ambient temperature (°C). Changes of the peaks’ concentration profiles are accompanied by the changing values (originally published in [3]).
