文摘

Density and viscosity of binary mixtures of D2EHPA + solvents were reported at T = (303.15–333.15) K, 0.1 MPa. A good correlation in density and viscosity between experimental and all models was confirmed by < 2.0 %RAD. Excess molar volume, apparent molar volume and thermal expansion coefficient were calculated from density data. Viscosity deviations, thermodynamic properties of activation of viscous flow were calculated from viscosity data. Molecular interaction is the strongest in D2EHPA + kerosene mixture.
