Abstract
The separation of C 11C 14 branched-chain alcohols and their acetyl derivatives by gas chromatography on a fused-silica capillary column coated with heptakis (6-O- tert.-butyldimethylsilyl-2,3-di-O-diacetyl)-β-cyclodextrin dissolved in OV-1701 (1:1) was studied. It is demonstrated that the separation of positional isomers of these alcohols and their acetyl derivatives on this stationary phase is poorer than that on Carbowax 20M. Enantiomers of the alcohols were resolved on this stationary phase at temperatures below 110°C, whereas enantiomers of their acetyl derivatives were not resolved under similar conditions.
