Abstract :Liquid crystal insert ignore into journalissuearticles values(LC); compound 4-Benzyloxyphenyl 4-[4-insert ignore into journalissuearticles values(n-dodecyloxy);benzoyloxy]benzoate insert ignore into journalissuearticles values(BDBB); was prepared and characterized. Inverse gas chromatography insert ignore into journalissuearticles values(IGC); was to be a beneficial analysis method for the research of thermodynamic characteristics of the new LC. Acetate and alcohol isomers were used to examine LC selectivity via the IGC technique at temperatures between 333.2 K and 483.2 K. The retention diagrams of n-heptane, n-octane, n-nonane, n-decane, undecane, dodecane, tridecane, n-butyl acetate, isobutyl acetate, ethyl acetate, n-propylbenzene, isopropylbenzene, ethylbenzene, chlorobenzene, and toluene on BDBB were plotted with temperatures of 483.2-493.2 K. Flory-Huggins interaction parameter and weight fraction activity coefficient at infinite dilution were researched for BDBB.
