THE GC SEPARATION OF C2-NAPHTHALENE ISOMERS USING CYCLODEXTRINS AND CROWN ETHERS

The twelve structural C2 isomers of naphthalene are resolved on a single capillary column using alpha, beta, or gamma-cyclodextrin as the stationary phase. A change in elution order is seen upon going from alpha to beta and then gamma-cyclodextrin which can be related to the size of the cyclodextrin...

Zusammenfassung:	The twelve structural C2 isomers of naphthalene are resolved on a single capillary column using alpha, beta, or gamma-cyclodextrin as the stationary phase. A change in elution order is seen upon going from alpha to beta and then gamma-cyclodextrin which can be related to the size of the cyclodextrin cavity and the stereochemical fit of the isomer. A crown-ether column and a liquid-crystal column were found to be unable to separate all of the isomers.
