N2 - Density and speed of sound have been measured for pure components such as furan, 2-5-dimethylfuran (DMF), nmethyldiethanolamine (MDEA), diethylene glycol (DEG), tri ethylene glycol (TEG), and dimethylacetamide (DMA) using an Anton Paar (DSA-5000) vibrating U-tube densitometer in the temperature range of 278.15 to 343.15 K and ambient pressure (100 kPa). Density and speed of sound have been measured for furan + MDEA, furan + DEG, furan + TEG, and furan + DMA in the temperature range of 278.15 to 303.15 K, whereas for DMF +DMA, the temperature range is 283.15 to 343.15 K. Excess molar volume has been calculated for all binary systems. The Redlich−Kister model is used to correlate the experimental data. In order to identify the impact of molecular interactions participating significantly in the excess molar volume, the prigogine−Flory−Patterson model is selected to correlate and predict the deviations for excess molar volumes of the binary mixtures.
