Szulik

It should also be mentioned that Szulik and Sowa [44] successfully separated enantiomers of some fatty hydroxyl acids such as DL-a-hydroxypalmitic- and DL-12-hydroxy stearic acid using 1% L-alanine and 2% L-alanine as mobile phase additives, respectively, with silica gel plates serving as a stationary phase. Besides, these authors presented enantioseparation of DL-12-hydroxyoleic acid using chiral plates [44].
