Abstract: High Resolution Image Download MS PowerPoint Slide The vapor pressures of the binary mixtures { N, N -dimethylacetamide + 1,3,5-trimethylbenzene, + propan-2-ol, or + dimethyl sulfoxide (DMSO)} and their pure components were measured using a static apparatus in the temperature range of 273.15–363.15 K. Semiempirical correlations as described by the Antoine equation were used to correlate the obtained results. The excess Gibbs function G E was evaluated for several constant temperatures and fitted to the Redlich–Kister equation. Positive deviations in G E are shown by the binary systems { N, N -dimethylacetamide + 1,3,5-trimethylbenzene, or + DMSO} in all investigated temperatures over the whole composition range, where a negative deviation in G E in all temperatures studied over the whole composition range is observed for the ( N, N -dimethylacetamide + propan-2-ol) binary system. Additionally, NRTL and UNIQUAC models were used for the correlation or prediction of the total pressure.
