摘要

在303.15 K - 318.15 K(∆T = 5k)和常压下，测量了糠醇与三种酮即苯乙酮、环戊酮和环己酮的纯混合物和二元混合物的超声速度(U)和密度(ρ)。根据实验数据确定了过量/偏差参数，即过量分子间自由长度(LfE)、每摩尔过量体积(VmE)和等熵压缩偏差(∆κs)。采用Redlich-Kister多项式方程拟合多余函数的参数，并估计了标准差。过量性质的结果得到了每摩尔部分体积研究的支持。为了支持热力学结果，将Prigogine-Flory-Patterson理论应用于过量摩尔体积。

Molecular association studies through physicochemical properties and application of Prigogine-Flory-Patterson theory to binary liquid mixtures of furfuryl alcohol with acetophenone, cyclopentanone and cyclohexanone

Speed of ultrasound (U), density (ρ) of pure and binary mixtures of furfuryl alcohol with three ketones, viz., acetophenone, cyclopentanone and cyclohexanone have been measured at temperatures 303.15 K - 318.15 K (∆T = 5 K), at atmospheric pressure. Excess/deviation parameters namely, excess intermolecular free length ( $L_{f}^{E}$ ), excess volume per mole ( $V_{m}^{E}$ ) and deviation in isentropic compressibility (∆κ_s) have been determined from the experimental data. Redlich-Kister polynomial equation has been considered for the fitting parameters of excess functions and the standard deviation is estimated. The results of excess properties are supported by partial volume per mole studies. To endorse the thermodynamic results, Prigogine–Flory–Patterson theory has been applied for excess molar volumes.

期刊介绍： Chemical Data Collections (CDC) provides a publication outlet for the increasing need to make research material and data easy to share and re-use. Publication of research data with CDC will allow scientists to: -Make their data easy to find and access -Benefit from the fast publication process -Contribute to proper data citation and attribution -Publish their intermediate and null/negative results -Receive recognition for the work that does not fit traditional article format. The research data will be published as ''data articles'' that support fast and easy submission and quick peer-review processes. Data articles introduced by CDC are short self-contained publications about research materials and data. They must provide the scientific context of the described work and contain the following elements: a title, list of authors (plus affiliations), abstract, keywords, graphical abstract, metadata table, main text and at least three references. The journal welcomes submissions focusing on (but not limited to) the following categories of research output: spectral data, syntheses, crystallographic data, computational simulations, molecular dynamics and models, physicochemical data, etc.
