摘要：
The ballast-free constant-volume piezometer technique is used for measuring the p, ρ, T dependences of aqueous solutions of aliphatic alcohols (methanol, ethanol, and 1-propanol) with 0.2, 0.5, and 0.8 mole fraction of alcohol in the temperature range from 373.15 to 623.15 K and at pressures up to 50 MPa for different values of density. The data of p, ρ, T measurements in the near-critical region are used to determine the parameters of critical state of solutions as a function of composition. Diagrams are constructed of projections of lines of critical points of thermodynamic surface in different planes.
