摘要： 把高温液晶双-(对正烷氧基苯甲酸)-对-联苯二酚酯类(烷基为丙基、丁基、戊基、己基、庚基和壬基)作气相色谱固定液分离菲、蒽和咔唑.用半米色谱柱测定各个化合物的相对保留值.实验结果说明端基为丁烷氧基和戊烷氧基的液晶(BPBBB和BPBAmB)最好.在BPBAmB柱上16分钟内可满意地把菲、蒽和咔唑分离开.

Abstract: The high-temperature liquid crystals p-biphenylene bis-(p-n-alkoxy-benzoate) homologs, in which alkyl group is propyl, butyl, amyl, hexyl, heptyl and nonyl, have been used as stationary phases for gas-liquid chromatographic separation of ph'enanthrene, anthracene and car-bazole. For comparsion some conventional liquid phases such as OV-101, OV-25, OV-210, OV-225 and Versamide-930 were studied as well.To find some better liquid phases relative retention was determined on 0.5m columns packed with these stationary phases. It is found that BPBBB (with Butyl group) and BPBAmB (with Amyl group) are better to separate the mixture of phenanthrene, anthracene and carbazole. On a 0.5m column packed with the liquid crystal BPBAmBon Chromosorb W NAW, the mixture can be separated satisfactorily within 16 minutes.
