Thermodynamic functions of the mixing of methacrylic acid in organic solvents

Аннотация

The saturated vapor pressure over solutions of methacrylic acid is measured tensimetrically in acetonitrile, benzene, hexane, 1,2-dichloroethane, and acetic acid is measured tensimetrically at 290–350 K. The composition of equilibrium phases, the activity coefficients of the components, and the thermodynamic functions of the mixing (H^E, G^E, S^E) of the investigated solutions are calculated from the temperature dependence data.
