Application of capillary column gas chromatography in industrial analysis ( VII ) - Analysis of disubstituted benzene isomers using peralkyl-β- cyclodextrin as the stationary phases

Describes a method of separation for disubstituted benzene isomers using capillary columns coated with peralkylated β-cyclodextrins. Three peralkylated β-cyclodextrins, i.e. permethyl-, perpropel-and perpentyl-β-cydodextrins were synthesized, and the capillary columns were coated with these stationary phases. A number of disubstituted benzene isomers were separated using a 10m long column coated with these stationary phases, e.g. xylene, crysol, dimethyphenol, didorobenzene, dibromobenzene, nitrochloro benzene, and nitrobro mo benzene isomers.
