摘要
利用毛细管色谱法研究了二氯取代苯,氯甲基苯的六种异构体在4种高分子液晶固定液中的溶解熵和溶解焓以及溶液的相转变温度,并从各溶质分子的构形和分子间相互作用特征的角度对所得结果进行了分析和讨论.
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.
