Key words: temperature, pressure, density, concentration, phase, fluid, equation of state, compressibility factor, reduced parameters

The results of thermal and thermodynamic properties (diagrams of state) calculation of water-aliphatic alcohol (methanol, ethanol, n-propanol) systems in liquid and vapor phases, as well as in the state of supercritical fluid are presented. They are based on the equation of state that represents the compressibility factor as power series of reduced density (ω = ρ/ρcr) and temperature(t = T/Tcr)
\(Z=\frac{\rho}{RT\rho_m}=1+\sum_{i=1}^{m}\sum_{j=0}^{n_i}\frac{a_{ij}\omega^i}{\tau^j}\)
and describes the experimental р, ρ, Т, х-relations with an average relative error 1.2%.
