A Study of the Solution Entropies and Solution Enthalpies of Substituted Benzene Isomers in Polymeric Liquid Crystals

Phase transition temperatures of stationary liquid and molar solution entropy as wb as solution enthalpy of three dichloro -benzene isomers and three chlorochlorotoluene isomers in four polysiloxane liquid crystal stationary phases (PLC-1, PLC-2,PLC-3, PLC-4) are deternined by capillary gas-liquid chromatograhy.The results are interpreted and analysed in terms of the interaction and configuration of the solute molecule.
