Abstract
- • Compression of water + acetamide mixture were measured. • Measurements were performed at pressures to 100 MPa and temperatures from 278.15 to 323.15 K. • Molar isothermal compression and isobaric expansion of the mixture were evaluated. The density ρ at atmospheric pressure and compression ratios k = Δ V / V o of the {water (1) + acetamide (2)} mixture in the range of temperature from 278.15 K to 323.15 K (278.15, 288.15, 298.15, 308.15, 323.15), pressures from 10 to 100 MPa (10, 25, 50, 75 and 100) and in a wide range of compositions (maximum mole fraction of acetamide (AA) x 2 = 0.3875) were measured in the work. The partial molar volumes of both components V ¯ 1 and V ¯ 2 in the mixture, molar isothermal compression K T , m , molar isobaric thermal expansion E P , m , isochoric coefficient of thermal pressure β V , and internal pressure of the mixture P int were calculated. The volume characteristics for an infinitely dilute AA solution in water: limiting partial molar volumes V ¯ 2 ∞ , limiting partial molar isothermal compression K ¯ T ,2 ∞ , and limiting partial molar isobar expansion E ¯ P ,2 ∞ were calculated. The obtained results are discussed from the standpoint of interactions of solute-solvent and solute-solute. The obtained results are discussed in terms of solute-solvent and solute-solute interactions. [ABSTRACT FROM AUTHOR]
