ResumoVapor-liquid-liquid equilibria in mixtures of dimethyl ether and water were investigated in a static equilibrium apparatus at pressures up to 1 MPa and temperatures 250 K < T < 350 K. Gas-solubilities, mutual liquid solubilities as well as vapor pressures of the immiscible two liquid phases in the system methyl chloride - water were determined. The conditions for the formation of a CH3Cl-hydrate were also investigated. Parameters of several gE-models were fitted to the experimental data and the reproducibility of the data with the gE-models was checked. New UNIFAC-parameters for the ether aliphatic - water interaction are reported.
