PERMETHYL-BETA-CYCLODEXTRIN, CHEMICALLY BONDED TO POLYSILOXANE - A CHIRAL STATIONARY PHASE WITH WIDER APPLICATION RANGE FOR ENANTIOMER SEPARATION BY CAPILLARY GAS-CHROMATOGRAPHY

Underivatized alkanediols and alkylcarboxylic acids, hydroxy(di)carboxylic acid methyl esters and cyanohydrins, as well as alkanes and derivatized amino acids : enantiomeric mixtures of all of these compound classes have been shown to be separable by gas chromatography on the new stationary phase permethylpolysiloxane permethylcyclodextrin 1. A column containing this material can be programmed for use up to 280 °C even though the substance is neither cross‐linked nor chemically bonded to the glass surface. Separations described here were performed at temperatures between 100 and 200 °C. (Figure Presented.) Copyright © 1990 by VCH Verlagsgesellschaft mbH, Germany
