Abstract
The vapor-liquid equilibrium (VLE-pressure, temperature, and composition of coexisting vapor and liquid phases) was directly determined by the ebullio metric method for the system formed by 2-ethoxy-ethanol with phenol. An aze otrope has been found. The experimental results were correlated by means of an equation of state (AEOS) that is capable of reproducing the VLE for ass ociating and reacting systems over a wide range of pressure and temperature with accuracy similar to the experiment uncertainty. Such results are hard to obtain with equations representing activity coefficients.
