摘要

本文讨论了2-（2-丁氧乙氧基）乙醇与仲胺（二异丙胺、二正丁胺）和叔胺（三正丁胺）二元混合物的研究。分别在温度T = 298.15、303.15和308.15 K和常压下测量了这些二元混合物的ρ、u和η。利用实验测量数据计算了各种多余、偏差和热声参数。研究了这些混合物中不同分子间相互作用的类型和容易程度。计算的参数证实了不同分子之间存在强相互作用。多余参数和偏差参数拟合为Redlich-Kister多项式。利用最小二乘法计算的标准差检验了该方程的适用性。

Thermodynamic studies of binary liquid mixtures of 2-(2-butoxyethoxy) ethanol with diisopropylamine, di-n-butylamine and tri-n-butylamine at 298.15, 303.15 and 308.15 K

Present discussion embodies the studies on binary mixtures containing 2-(2-butoxyethoxy) ethanol with secondary amines (diisopropylamine, di-n-butylamine) and tertiary amine (tri-n-butylamine).ρ, u and η of these binary mixtures were measured at temperatures T = 298.15, 303.15 and 308.15 K and at atmospheric pressure. Various excess, deviation and thermo acoustic parameters were calculated using the experimentally measured data. Results were investigated for type and ease of intermolecular interactions among unlike molecules in these mixtures. Presence of strong interactions among unlike molecules has been confirmed by the calculated parameters. Excess and deviation parameters were fitted to Redlich-Kister polynomial. Ability of this equation was tested using the standard deviation calculated with the help of least square method.

期刊介绍： The Journal of Chemical Thermodynamics exists primarily for dissemination of significant new knowledge in experimental equilibrium thermodynamics and transport properties of chemical systems. The defining attributes of The Journal are the quality and relevance of the papers published. The Journal publishes work relating to gases, liquids, solids, polymers, mixtures, solutions and interfaces. Studies on systems with variability, such as biological or bio-based materials, gas hydrates, among others, will also be considered provided these are well characterized and reproducible where possible. Experimental methods should be described in sufficient detail to allow critical assessment of the accuracy claimed. Authors are encouraged to provide physical or chemical interpretations of the results. Articles can contain modelling sections providing representations of data or molecular insights into the properties or transformations studied. Theoretical papers on chemical thermodynamics using molecular theory or modelling are also considered. The Journal welcomes review articles in the field of chemical thermodynamics but prospective authors should first consult one of the Editors concerning the suitability of the proposed review. Contributions of a routine nature or reporting on uncharacterised materials are not accepted.
