ABSTRACT The density (ρ) and kinematic viscosity (v) data of polyethylene glycol 300 (PEG) + N, N-Dimethylformamide (DMF) binary mixture were determined under atmospheric pressure and six temperatures of T = (293.15–318.15) K. From these experimental results, the thermodynamic parameters like excess molar volume (V m E), apparent molar volume (Vφ, 1 and Vφ, 2) and partial molar volume ( and ), viscosity deviation (Δη) and excess Gibbs activation free energy (ΔG*E) were systemically counted, in which the standard deviation between the experimental and calculated data was estimated by fitting the Redlich-Kister formula. The intermolecular interaction of DMF with PEG was analysed by FTIR and UV-vis spectral technologies.

摘要 聚乙二醇 300 (PEG) + N, N-二甲基甲酰胺 (DMF) 二元混合物的密度 (ρ) 和运动粘度 (v) 数据是在大气压和 T = (293.15–318.15) K 的六个温度下测定的。这些实验结果、热力学参数如过量摩尔体积 (V m E)、表观摩尔体积 (Vφ, 1 and Vφ, 2) 和偏摩尔体积 ( and )、粘度偏差 (Δη) 和过量吉布斯活化自由能 (ΔG *E) 进行系统计数,其中通过拟合 Redlich-Kister 公式估计实验数据和计算数据之间的标准偏差。通过FTIR和UV-vis光谱技术分析DMF与PEG的分子间相互作用。
