Title:
トリメチルシクロペンテン誘導体の鏡像異性体比を決定する方法
Document Type and Number:
Japanese Patent JP4027315
Kind Code:
B2
Abstract:
The invention relates to a method for determining the enantiomer ratio of trimethylcyclopentene derivatives of structure (I), wherein Z is an alkyl radical having 1-10 C atoms, can be saturated or olefinically unsaturated, straight-chained or branched and which is substituted by an OH or CHO group, by means of capillary gas chromatography, wherein a stationary phase is applied containing a compound selected from the group of Heptakis-(2,3-di-O-methyl-6-O-tert.-butyldimethylsily)-beta-Cyclodextrin and Heptakis-(2,3-di-O-acetyl-6-O-tert.-butyldimethylsilyl)-beta-Cyclodextrin and at least one polysiloxane, wherein the mixing ratio of Cyclodextrin derivatives and polysiloxanes is adjusted to a value ranging from 10:90 to 50:50.
