Thermophysical Properties of Mixtures of 2-Ethylhexanoic Acid and Ethanol

Abstract

Mixtures of 2-ethylhexanoic acid (EHA) and ethanol are common solvents for precursor solutions in spray flame synthesis for the production of nanoparticles, however, no thermophysical data are available in the literature for these mixtures. Therefore, in this work, the density, viscosity, thermal conductivity, isobaric heat capacity, and self-diffusion coefficients of mixtures of EHA and ethanol were measured at atmospheric pressure and temperatures between 293.15 and 333.15 K. Additionally, isobaric vaporliquid equilibria of the system were measured at pressures between 20 and 80 kPa. Empirical models were parametrized and are provided for all measured properties for convenient use in spray flame synthesis process simulations and related applications.
