ABSTRACT

Isobaric vapor-liquid equilibrium data at 95.96 kPa for the three binary systems of dimethoxymethane with methyl tert-butyl ether, diisopropyl ether, and 2-propanol are determined. A Swietoslawski-type ebulliometer is used for the measurements. The experimental T-x data are used to estimate Wilson parameters, and the parameters is in turn are used to calculate vapor compositions and activity coefficients. The activity coefficients are useful for calculating the excess Gibbs function. None of the systems studied here exhibit azeotropes. Excess Gibbs function values are positive over the entire range of composition for all of the systems.
