摘要
胆甾型苯并-15-冠-5(简称CH-B-15-C-5)在不同温度范围内的相态不同,在同一温 度范围内因处理方式不同而物性亦相去甚远,用其作成的GC固定相兼具气固色谱(GSC)、 普通气液色谱(GLC)和冠醚液晶气液色谱(CL-GLC)多种功能。用该固定相在不同条件下对 乳酸和乳酸乙酯光学异构体混合物的分高效果进行了比较研究,并探讨了手性拆分机理。
Separation of optical isomers of lactic acid and ethyl lactate with cholesteryl liquid crystal crown (CH-B-15-C-5) as gas chromatographic stationary phase was studied in this paper. Some chromatographic characteristics of CH-B-15-C-5 were also studied. The results of separation of optical isomers were discussed.
