Abstract

The supercritical fluid chromatography (SFC) separation of the enantiomers of 1-phenyl-1-propanol on the chiral stationary phase Chiralcel OD under linear conditions is studied. Supercritical CO2 modified with methanol is used as a mobile phase. The effect of modifier concentration, pressure and temperature is studied. An empirical isotherm to account for the effect of density of the mobile phase and modifier concentration has been used to model the experimental results. It was observed that the selectivity and resolution were higher at 30 degrees C as compared to those at 40 degrees C.
