    (Mdpi, 2007) Topal, Giray; Tuemerdem, Recep; Basaran, Ismet; Guemues, Arzu; Cakir, Umit
    The constants of the extraction equilibrium and the distribution for dichloromethane as an organic solvent having low dielectric constant of metal cations with chiral Schiff bases, benzaldehydene-(S)- 2- amino- 3- phenylpropanol (I), o-hydroxybenzaldehydene(S)- 2- amino- 3- phenyl- propanol (II), benzaldehydene-(S)- 2amino- 3- methylbutanol (III) with anionic dyes [4-(2- pyridylazo)- resorcinol mono sodium monohydrate (NaPar), sodium picrat (NaPic) and potassium picrat (KPic)] and some heavy metal chlorides were determined at 25 degrees C. All the ligands have given strongest complexation for NaPar. In contrast, similar behaviour for both alkali metal picrates is not apparent in the complexation of corresponding ligands.
