Density and Speed of sound have been measured for pure components such furan, (DMF) 2-5-dimethylfuran, MDEA (n-methyldiethanolamine), DEG (diethylene glycol), TEG (triethylene glycol), and DMA (dimethylacetamide) using Anton Paar (DSA-5000) vibrating U-tube densitometer in a 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 a temperature range of 278.15 K to 303.15 K whereas for DMF + DMA, the temperature range is 283.15 K to 343.15 K. excess molar volume have 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.
