摘要：This article describes the thermodynamic parameters and phase behaviour of a Schiff Base Liquid crystal , the mesogene was synthesized in the five chemical reactions and characterized by FTIR , 1H and 13C - NMR techniques. The mesomorphic properties were studied using di fferential scanning calorimetry (DSC) and polarizing optical microscopy (POM) , T he retention diagrams of n - alkanes on the sta tionary phase were plotted at temperatures in °C between 100 and 170 by inverse gas chromatography technique. T he separation of n - alkanes was estimated using retention times in the infinite dilution region. T he t hermodynamic parameters of intermolecular in teractions between the stationary phase and n - alkanes (free energy, enthalpy, and entropy ) were calculated and the results were discussed.
