Addendum to “Volumetric properties of binary liquid-phase mixture of (water + glycerol) at temperatures of (278.15 to 323.15) K and pressures of (0.1 to 100) MPa” [J. Chem. Thermodyn. 79 (2014) 135–158]: Effect of pressure on excess thermodynamic characteristics of mixture water + glycerol

Abstract

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, ΔPo→PGmE, excess molar entropy, ΔPo→PSmE, excess molar enthalpy, ΔPo→PHmE, as well as the enthalpy of mixing of water and glycerol, HmE, at 100MPa. The mixing enthalpies of water and glycerol, HmE, became more exothermic with pressure increasing at all temperatures studied.
