摘要
The density (rho) and kinematic viscosity (v) in the scope of T = (298.15 to 323.15) K were systemically studied for 1,4-butanediol (BDO) (1) + dimethyl sulfoxide (DMSO) binary mixture with various compositions at atmospheric pressure. From the p and v values, the dynamic viscosity (eta) were also obtained. According to the above experimental values, viscosity deviation (Delta eta), excess molar volume (V-m(E)), partial molar volumes ((v(1)) over bar and (v(2)) over bar), apparent molar volume (V-phi,V-1 and V-phi,V-2) and isostatic pressing thermal expansion (alpha(p)) were determined. The rho, v(m)(E) and Delta eta values were fitted by using Jouyban-Acree model, Eyring equation, and Redlich-Kister equation, respectively. Additionally, the intermolecular interplay was analyzed using FTIR, NMR, and UV-vis spectra, which suggested the formation of hydrogen bonds between the hydroxyl H atoms in BDO and the O atoms in DMSO.
