Thermodynamic Properties of Solutions of Ethacrylic Acid in Acetonitrile and Acetic Acid
The saturated vapor pressure of ethacrylic acid solutions in acetonitrile and acetic acid was measured by a static tensimetric method in the temperature range of 295 to 355 K. The composition of the equilibrium phases as well as the activity coefficients were received from the experimental measurements of the temperature-dependent saturated vapor pressure. We then used the temperature and concentration dependent activity coefficients to calculate the excess thermodynamic functions of the solutions mixing (HE, GE, SE).
