TI  - Evaluation of the surface properties of 4-(Decyloxy) benzoic acid liquid crystal and its
use in structural isomer separation
AB  - The selectivity of 4-(Decyloxy) benzoic acid (DBA) liquid crystal in surface adsorption region (303.2–328.2 K) and thermodynamic region (423.2 – 433.2 K) was investigated by inverse gas chromatography at infinite dilution (IGC-ID). The selectivity parameters of the structural isomer series named butyl acetate, butyl alcohol, and amyl alcohol series were calculated for the DBA using IGC-ID technique. Additionally, the surface properties including dispersive surface energy $(gamma_S ^{D}),$ free energy (DGA S ), enthalpy $(DeltaH_A ^{S}),$, and acidity-basicity constants were calculated with net retention volumes obtained from IGC-ID experiment results. When the DHA S and $(DeltaG_A ^{S}),$ are constants, DBA surface was found to be an acidic character $(K_D/K_A cong 0.89).$
