Abstract
Abstract 2,3-Di-O-ethyl-6-O-tert.-butyldimethylsilyl-β and −γ-cyclodextrins (ETTBS-β- and −γ-CDs) are proposed as stationary phases for GC separation of enantiomers. The influence of different polarity polysiloxanes (PS-347.5, PS-086, OV-1701) as diluting phase on the separation capacity of these CD derivatives was also investigated. The results of ifETTBS-β- and −γ-CDs are compared to those of if2,3-di-O-methyl-6-O-tert.-butyldimethylsilyl-β- and−γ-cyclodextrins (ifMETBS-β- and−γ-CDs). The advantages of ETTBS-β- and −γ-CDs in terms of minimum opeative temperatures and separation capacity of the column are discussed. Each column coated with each of the new synthesized CD derivatives was evaluated by analysing a number of different racemates with different structures.
