摘要: Abstract Densities and viscosities of the binary system ethylene glycol (EG) (1) + dimethyl sulfoxide (DMSO) (2) over entire composition range were measured at T = (298.15, 303.15, 308.15, 313.15, 318.15, 323.15) K atmospheric pressure. Based on density viscosity data, excess molar volume, deviation, Gibbs free energy activation for viscous flow, apparent volumes calculated. These results fitted to a Redlich–Kister equation obtain coefficients estimate standard deviations between experimental calculated quantities. Meanwhile, from kinematic enthalpy flow entropy also In addition, based UV–vis FTIR spectral results, intermolecular interaction EG with DMSO was discussed.
