The ( p, ρ, T) properties of {(1− x 1− x 2)H 2O+ x 1CH 3OH+ x 2LiBr} over a wide range of state parameters are reported for the first time. The experiments were carried out in a constant volume piezometer over a temperature range from 298.15 K to 398.15 K, at x 1=0.58302, x 2=0.07148; x 1=0.31791, x 2=0.11693; x 1=0.14923, x 2=0.05489; x 1=0.10425, x 2=0.15356; x 1=0.04677, x 2=0.16341 from atmospheric pressure up to 60 MPa. The experimental uncertainties are Δ T=±3 mK for temperature, Δ P=±5·10 −2 MPa for high pressure and Δ P=±5·10 −4 MPa for atmospheric pressure, Δρ=±3·10 −2 kg· m −3 for density. A equation of state was derived for correlation of the experimental data of solutions.
