چکیده انگلیسی
Density and viscosity of the binary liquid system, tri-ethylene glycol (TEG) + dimethyl sulfoxide (DMSO), were studied over the whole composition range at T = (293.15, 298.15, 303.15, 308.15, 313.15 and 318.15) K under a pressure of 0.1 MPa. Based on these density and viscosity data, their excess molar volume (VmE), viscosity deviation (Îη), apparent molar volumes (VÏ,1 and VÏ,2) and partial molar volumes (V_1 and V_2) were determined, respectively. Their VmE and Îη values were then fitted to a Redlich-Kister equation to obtain the coefficient and the standard deviation. Additionally, the intermolecular interaction, obtained from FTIR and UV-Vis, indicated that hydrogen bonding between hydroxyl hydrogen atom in TEG and oxygen atom in DMSO was formed.
