The CH₃(CH₂)_uCOO(CH₂)_vCH₃ + n-alkane mixtures have been investigated on the basis of an experimental database containing effective dipole moments of esters, and excess molar functions of the systems: enthalpies ($H_{\mathrm{m}}^{\mathrm{E}}$), volumes ($V_{\mathrm{m}}^{\mathrm{E}}$), isobaric heat capacities ($C_{p\mathrm{m}}^{\mathrm{E}}$) and isochoric internal energies ($U_{V\mathrm{m}}^{\mathrm{E}}$) and by means of the application of the Flory model and the Kirkwood-Buff formalism. The situation of the mixtures within the$G_{\mathrm{m}}^{\mathrm{E}}$(excess molar Gibbs energy) vs. $H_{\mathrm{m}}^{\mathrm{E}}$diagram has also been briefly considered. Results indicate that dispersive interactions are dominant and that steric effects can explain some differences between solutions containing heptane and isomeric esters. Proximity and orientational effects are also discussed in diester + hexane mixtures. In the case of systems with a given alkane and different isomeric polar compounds, orientational effects become weaker in the order: n-alkanone > dialkyl carbonate > n-alkanoate. Results from the Kirkwood-Buff formalism indicate that the number of ester-ester interactions decreases in systems with alkyl ethanoates when the alkyl size increases and that preferential solvation between polar molecules decreases as follows: dialkyl carbonate > n-alkanone > n-alkanoate.

基于包含酯有效偶极矩和系统过量摩尔函数的实验数据库，研究了CH ₃ (CH ₂ ) _u COO(CH ₂ ) _v CH ₃  +  n -烷烃混合物：焓 ($H_{\mathrm{米}}^{\mathrm{乙}}$），体积（$V_{\mathrm{米}}^{\mathrm{乙}}$), 等压热容 ($C_{p\mathrm{米}}^{\mathrm{乙}}$）和等容内能（$U_{V\mathrm{米}}^{\mathrm{乙}}$）并通过应用 Flory 模型和 Kirkwood-Buff 形式主义。混合物内的情况$G_{\mathrm{米}}^{\mathrm{乙}}$（过量摩尔吉布斯能量）与$H_{\mathrm{米}}^{\mathrm{乙}}$图表也已被简要考虑。结果表明，分散相互作用占主导地位，空间效应可以解释含有庚烷和异构酯的溶液之间的一些差异。还讨论了二酯 + 己烷混合物中的邻近效应和定向效应。在具有给定烷烃和不同异构极性化合物的体系的情况下，取向效应按以下顺序变弱：正烷酮>碳酸二烷基酯>正烷酸酯。Kirkwood-Buff 形式主义的结果​​表明，当烷基尺寸增加时，具有乙酸烷基酯的体系中酯-酯相互作用的数量减少，并且极性分子之间的优先溶剂化按如下方式减少：碳酸二烷基酯 > 正烷酮>正烷酸酯。
