Density and Derived Properties of Binary Mixtures Containing {2-(Dimethylamino)ethyl Methacrylate plus Alcohols} at Temperatures from T = (293.15 to 313.15) K and Pressures of up to 35 MPa

In this study, experimental density data (rho) for binary liquid mixtures containing {2-(dimethylamino)ethyl methacrylate (DMAEMA) + methanol, or + ethanol, or + 1-propanol, or + 1-butanol, or + 1-pentanol} have been measured over the entire composition range at temperatures from T = (293.15 to 313.15) K and pressures of up to 35 MPa. Density measurements were obtained using an Anton Paar DMA 4500 vibrating-tube densimeter coupled to an external Anton Paar DMA HP high-pressure measuring cell. The experimental results for density have been fit to the Tait-Tammann equation and used to calculate the isothermal compressibility (kappa(T)), the thermal expansion coefficient (alpha(p)), and the internal pressure (pi). The excess molar volume (V-m(E)) values have still been calculated and used to test the applicability of the extended real associated solution model (ERAS model) and the Prigogine-Flory-Patterson theory (PFP Theory). The thermodynamic results suggest that structural and chemical effects must outweigh physical effects.
