| Popis: | Density (ρ) and dynamic viscosity (η) for the binary system of tetraethylene glycol (TeEG) and dimethyl sulfoxide (DMSO) were measured at T = (293.15 to 318.15) K with the step of 5 K and surrounding ambient pressure. From experimental ρ and η values, the excess molar volumes (VmE), apparent molar volumes (Vφ,1 and Vφ,2), partial molar volumes ( V 1 ¯ and V 2 ¯ ), viscosity deviations (∆ η) and the thermal expansion coefficient (αp) were calculated. The pure solvents and other concentrations were characterized using UV–Vis, fluorescence, FTIR, and 1H NMR spectral technologies, and the spectral results illuminated that hydrogen bonds were formed between TeEG and DMSO. |
