R. Reinhardt et al., ENANTIOMER SEPARATION OF SIDE-CHAIN FLUORINATED ALKYLBENZENES BY CAPILLARY GAS-CHROMATOGRAPHY ON CYCLODEXTRIN PHASES, Chromatographia, 39(3-4), 1994, pp. 192-199
The separation of racemic side-chain fluorinated alkylbenzenes and bro
mofluorinated analogues by capillary gas chromatography using permethy
lated alpha, beta and gamma-cyclodextrins dissolved in polysiloxanes o
f different polarity as stationary phases is described. The influence
of the achiral polysiloxane matrices on the separation of enantiomers
is discussed in the light of the results obtained with the different p
hases. For a part of the tested compounds thermodynamic data are deter
mined which describe the interaction of enantiomers with the stationar
y phase. The mechanism of separation is discussed on this basis and by
comparison with data for structurally similar compounds.
