Isothermal P-x data, isobaric T-x-y data, and enthalpies of mixing were measured for the binary systems of N-methylacetamide + aniline, decane, naphthalene, phenol, water, or ethylene glycol using a static apparatus, a Swietoslawski-ebulliometer, an isothermal flow calorimeter, and a Tian-Calvet batch calorimeter. The experimental data were correlated with the help of the NRTL or the UNIQUAC model, for which temperature dependent interaction parameters were fitted simultaneously to VLE and H-E data.
