TY - JOUR ID - TI - Nematic Mesogen with 1,3,4-Oxadiazole Unit as Stationary Phase in Gas-Liquid Chromatography AU - Zainab Jasim AU - Nasreen R. Jber PY - 2021 VL - 24 IS - 3 SP - 30 EP - 37 JO - Al-Nahrain Journal of Science مجلة النهرين للعلوم SN - 26635453 26635461 AB - This paper is the first that deals with the new synthesis of nematic liquid crystal titledbis-[5-yl-phenylbenzidine-4`-butyloxyphenly-2-yl-1,3,4-oxadiazole] and secondly discusses research on materials that can be used in stationary phase by using (GLC) as a type of chromatography. The usage of bis-[5-yl-phenylbenzidine-4`-butyloxyphenly-2-yl-1,3,4 oxadiazole ] nematic phase has resulted in a lot of superb separations of a lot of poly aromatic hydrocarbons. The retention time change in an unusual way with temperature, appearance a significant increase at the normal liquid transmission point; as expected, that impact is reduced with further planar compounds. FT-IR and 1HNMR were used to characterize the synthesized chemical structure, and POM and DSC were used to investigate the liquid crystalline characteristics.
