Abstract
Branchedα-cyclodextrins (CDs) such as glucosyl-α-CD(G-α-CD) were found to be very effective reagents for selective liquid-liquid extraction of xylene isomers and ethylbenzene since their inclusion complexes did not precipitate and handling of solids was not necessary. Reaction temperatures higher than room temperature did not increase the yield. The inclusion complexation proceeded fast. The liquid-liquid extraction process was found to be energy-saving and not time-consuming.
