Experimentally determined volumetric properties of the liquid binary mixture of {water (1) + glycerol (2)} were processed to calculate the changes of the following thermodynamic parameters with pressure: excess molar Gibbs free energy, Delta(Po -> P)G(m)(E), excess molar entropy, Delta S-Po -> P(m)E, excess molar enthalpy, Delta H-Po -> P(m)E, as well as the enthalpy of mixing of water and glycerol, H-m(E), at 100 MPa. The mixing enthalpies of water and glycerol, H-m(E), became more exothermic with pressure increasing at all temperatures studied. (C) 2014 Elsevier Ltd. All rights reserved.
