对芳羧酸酯液晶(MPBHPB)和杯芳烃(戊基苯基间苯二酚杯芳烃)两种化合物组成的混合固定相,以不同比例涂渍成毛细管柱,考察了它们对二元取代苯位置异构体的保留行为,从比较溶质在混合固定相(1:1)及单一固定相上的分离因子α得出,这种混合固定相产生“协同效应”,对产生“协同效应”的原因作了探讨.
The mixed stationary phases consisting of the aromatic carboxylate liquid crystal (MPBHPB) and the calixarene (pentyl phenyl resorcinarene) were coated in different proportions into capillary columns. The effects of their adsorption on dibasic substituted benzene The retention behavior of the positional isomers, derived from the separation factor α compared to the solute in a mixed stationary phase (1: 1) and a single stationary phase, produces a “synergistic effect” of producing a “synergistic” The reason is discussed.
