摘要：

By the use of extrathermodynamic relationships, i.e., linear free energy relationship and linear .DELTA.H-pKb relationship, a retention mode change induced by the change of mobile phase composition for the liquid chromatographic separations of several substituted anilines using amino and diamine-bonded phase columns is demonstrated. The change is not obvious when a silica column is used. Possible interaction modes are proposed at a molecular level as static views of the retention process involving hydrogen bonding as the interaction force.
