The inverse gas chromatography (IGC) method was used to obtain thermodynamic and surface properties of the thermotropic liquid crystalline material, 4-[4-((S)-citronellyloxy)benzoyloxy] benzoic acid (CBB). Liquid crystal (LC) selectivity was investigated using the alcohol and acetate isomers by the IGC method at temperatures between 338.2 K and 463.2 K. The retention diagrams of n-decane, undecane, dodecane, tridecane, n-butyl acetate, iso-butyl acetate, ethylbenzene and chlorobenzene on CBB were plotted in the temperature range between 468.2 K and 493.2 K. The specific retention volume, V-g(0), Flory-Huggins interaction parameter, x12, equation-of- state interaction parameter, x*12, the partial molar heat of sorption, Delta H-1(s), the partial molar heat of mixing,. similar to H11, the molar heat of vaporization,. Delta HV and the weight fraction activity coefficient, O11, were determined.
