dc.description.abstractAn inverse gas chromatography (IGC) study of thermodynamic interactions of a new chiral calamitic liquid crystalline 54(S)-3,7-Dimethyloctyloxy)-2-[[[4-(dodecyloxy)phenyl]imino]methyl]phenol (DODPIMP) with some solvents was presented. The retention diagrams of the solvents on the DODPIMP were plotted by specific retention volumes, V-g(0) at temperatures between 373.2 and 393.2 K. The Flory-Huggins interaction parameter, chi(infinity)(12), the weight fraction activity coefficient, Omega(infinity)(1) and selectivity coefficients, alpha, of the structural isomers were determined for the DODPIMP liquid crystal. To characterize the surface properties of, retention diagrams of several non-polar and polar solvents on the DODPIMP were plotted by net retention volumes, V-N in the temperature rangefrom 303.2 to 318.2 K. The dispersive surface energy, the thermodynamic adsorption parameters and the acid-base constants of the compound in the crystalline phase were determined. The results indicated a basic character for the surface of DODPIMP at the studied conditions. (C) 2016 Elsevier B.V. All rights reserved.
