Study on extraction kinetics of α-cyclopentylmandelic acid enantiomers with hydroxyethyl-β-cyclodextrin as chiral selector

The kinetic study on reactive extraction of α-cyclopentyl mandelic acid (α-CPMA) enantiomers was performed in a Lewis cell (a) using hydroxyethyl-β-cyclodextrin as chiral extractant. Under different conditions, concentrations of α-CPMA curve over time were obtained (b).144
