VAPOR-LIQUID-EQUILIBRIUM DATA AT 25-DEGREES-C FOR 6 BINARY-SYSTEMS CONTAINING METHYL ACETATE OR METHANOL, WITH DICHLOROMETHANE, CHLOROFORM, OR 1,2-TRANS-DICHLOROETHYLENE

Isothermal vapor-liquid equilibrium (VLE) data, at 25-degrees-C were determined by a saturation method for each of the six methanol or methyl acetate binary systems with dichloromethane, chloroform, and 1,2-trans-dichloroethylene. The experimental data satisfy the Redlich-Kister consistency test, and were correlated with five Gibbs free energy models. All the binary mixtures of methanol with the chlorinated compounds exhibit strong positive deviations from ideality while the mixtures of methyl acetate with the chlorinated compounds present negative deviations from ideal behavior.
