气相色谱法研究某些异构物在对苯二酚芳羧酸酯类液晶中的溶液热力学
摘要:
在不同温度下测量了二甲苯异构体、二氯苯异构体以及联苯和二苯甲烷在三种对苯二酚芳羧酸双酯类液晶向列相中的活度系数、偏摩尔过最焓和偏摩尔过量熵, 所测结果按溶液统计理论的观点作了定性的解释。

THERMODYNAMIC STUDIES ON SOLUTIONS OF SOME ISOMERS IN AROMATIC DIESTER LIQUID CRYSTALS BY GAS-LIQUID CHROMATOGRAPHY
Abstract:
Using p-phenylene-di-n-alkoxybenzoate homolo us series as stationary liquid, the infinite dilution activity coefficients γ_i~∞, partial molar excess enthalpies H_i~E and entropies S_i~E of xylene isomers, dichlorobenzene isomers, diphenyl and diphenylmethane have been measured in the nematic phase of three liquid crystals. The studied liquid crystal series have the following general formulas,
where n=6(PBH_xB), n=7(PBH_pB) and n=8(PBOB)
The results were explained from theview point of statistical theory of solutions.
