Isothermal vapor-liquid equilibria for eight binary systems of the reactive system ethylene glycol-acetic acid have been measured using a static VLE-equipment. Furthermore, excess enthalpies were determined with the help of an isothermal flow-calorimeter. Additionally, vapor pressure and density measurements of the monoacetylated ethylene glycol were carried out. (c) 2007 Elsevier B.V. All rights reserved.
