High-pressure vapor-liquid equilibrium for dimethyl ether plus ethanol and dimethyl ether plus ethanol plus water

The first part of this paper is a review of experimental methods and the high-pressure phase behavior of dimethyl ether systems for which data have been published between 1932 and 1999. For the systems investigated, the references, temperatures, pressures, cell volumes, and experimental procedures are reported. The second part of this paper is high-pressure vapor-liquid equilibrium (VLE) data for the systems dimethyl ether (DME) + ethanol at (332.95, 353.25, and 373.15) K and dimethyl ether + ethanol + water at (333.55, 353.55, and 373.65) K. The experimental data are correlated using the Elliott-Suresh-Donohue (ESD-EOS) and Peng Robinson (PR-EOS) equations of state.
