Liquid crystal (LC) compound 4-Benzyloxyphenyl 4-[4-( -dodecyloxy)benzoyloxy]benzoate (BDBB) was prepared and characterized. Inverse gas chromatography (IGC) was to be a beneficial analysis method for the research of thermodynamic characteristics of the new LC. Acetate and alcohol isomers were used to examine LC selectivity via the IGC technique at temperatures between 333.2 K and 483.2 K. The retention diagrams of -heptane, -octane, -nonane, -decane, undecane, dodecane, tridecane, -butyl acetate, isobutyl acetate, ethyl acetate, -propylbenzene, isopropylbenzene, ethylbenzene, chlorobenzene, and toluene on BDBB were plotted with temperatures of 483.2-493.2 K. Flory-Huggins interaction parameter and weight fraction activity coefficient at infinite dilution were researched for BDBB.
制备并表征了液晶(LC)化合物4-苄氧基苯基4-[4-( -十二烷氧基)苯甲酰氧基]苯甲酸酯(BDBB)。反相气相色谱法(IGC)是研究新型液晶热力学特性的一种有益分析方法。在333.2 K至483.2 K的温度范围内,通过IGC技术使用乙酸酯和醇异构体来检测液晶的选择性。绘制了483.2 - 493.2 K温度下庚烷、辛烷、壬烷、癸烷、十一烷、十二烷、十三烷、乙酸丁酯、乙酸异丁酯、乙酸乙酯、丙苯、异丙苯、乙苯、氯苯和甲苯在BDBB上的保留图。研究了BDBB的弗洛里-哈金斯相互作用参数和无限稀释下的重量分数活度系数。
