Chiral resolutions of trifluoroacetyl‐derivatized 1‐phenylalkylamines with different type and position of substituent were investigated by capillary gas chromatography by using heptakis(2,3‐di‐O‐methyl‐6‐O‐tert‐butyldimethylsilyl)‐β‐cyclodextrin diluted in OV‐1701 as a chiral stationary phase. The influence of column temperature on retention and enantioselectivity was examined. All enantiomers of meta‐substituted
采用七(2,3-二-O-甲基-6- O-叔-丁基二甲基甲硅烷基)-β-环糊精通过毛细管气相色谱法研究了具有不同取代基类型和位置的三氟乙酰基衍生化的1-苯基烷基胺的手性拆分OV-1701作为手性固定相。考察了柱温对保留和对映选择性的影响。可以取代间位取代分析物的所有对映体以及氟代分析物。温度对邻位有取代基的小胺的对映选择性有有利影响-位置。胺的立体异构中心的取代基类型也起关键作用,因为乙基基团导致对映体分离不良。在所有研究的分析物中,三氟乙酰基衍生化的1-(2'-氟苯基)乙胺表现出基线分离度,且分析时间最短。
