The adsorption of p-cyclodextrin polymer was studied on different silica beads, in water-organic solvent mixtures. A maximum adsorption on Lichrospher 100 A 5 Frn was observed for a polymer solution containing 70% acetone. Different crosslinking agents were used to stabilize the polymer layer on the
## Abstract Immobilized polysiloxane‐anchored permethyl‐β‐cyclodextrin (Chirasil‐Dex) with a cyclodextrin content of approximately 30 % by weight, previously employed as a versatile chiral stationary phase for the separation of enantiomers by GC, has been used for the separation of enantiomers by c
## Abstract Naphthylcarbamate‐substituted (3‐(2‐O‐β‐cyclodextrin)‐2‐hydroxypropoxy)‐propylsilyl‐appended silica gel (NSCD‐HPS) has been synthesized via a convenient liquid‐solid phase reaction on a silica gel surface. The chromatographic behavior of NSCD‐HPS in high‐performance liquid chromatograph
Immobilized chiral stationary phases (CSP)s from mono-6 A -azido-6 A -deoxy-perphenylcarbamoylated b-cyclodextrin were prepared using an extended application of the Staudinger reaction. Their application in preparative enantioseparations of racemic mixtures was demonstrated using atropine, bendroflu
