Abstract
The isothermal compressibility coefficients κ T , volumetric thermal expansion coefficients α, and pressure coefficients (∂p/∂T) v were calculated for water-N,N-dimethylformamide (DMFA) mixtures of 12 compositions over the temperature and pressure ranges 278–323.15 K and 0.1–100 MPa. The composition dependences of κ T passed minima, and the corresponding α and (∂p/∂T) v dependences passed maxima. The structural features of water and hydrophobic hydration effects were found to play a determining role in changes in the thermodynamic properties of water-DMFA solutions.
