ABSTRACT
Isothermal vapor-liquid equilibrium (VLE) data were measured, with a static-type apparatus, for binary systems of 1,2-dimethoxybenzene + 2-methoxyphenol, 1,2-dimethoxybenzene + tert-butanol, 2-methoxyphenol + tert-butanol, 1,2-dimethoxybenzene + morpholine, and 2-methoxyphenol + morpholine in the temperature range 333.15 K to 443.15 K. No azeotropes were found. While the tert-butanol-containing systems exhibited positive deviations from Raoult's law, the morpholine-containing systems showed negative deviations. The VLE data were correlated with the NRTL and the UNIQUAC models. Both models were equally satisfactory in representing the results.
