Beschreibung

General description

Phase: nicht gebunden; 25% 2,3-Di-O-acetyl-6-O-TBDMS-β-cyclodextrin in SPB-20 Poly(20% phenyl/80% dimethylsiloxan)

Application

β-DEX^™-325 column was used in gas-liquid chromatography (GLC), for determination of (R)-1-O-acetyl-2-ethyl-1,3-propanediol, formed from 2-Ethyl-1,3-propanediol 1 and its related di-O-acetate, by partial chemoenzymatic acetylation and deacetylation, by Pseudomonas fluorescens lipase. β -Dex^™-325 capillary column was also used for resolving 8-acetoxylinalool enantiomers, in an experimental study done in order to study the origin of the enantioselectivity in the biosynthesis of the lilac compounds in Actinidia arguta flowers.
