Zusammenfassung:Solid−liquid equilibria of 14 binary systems containing various amides or sulfolane with organic compounds have been measured by a visual technique. The substances investigated are important and often used as selective solvents in the chemical industry, for example for extractive distillation or extraction. Assuming eutectic behavior for all systems, the experimental data are compared with the results of the Modified UNIFAC (Dortmund) model.
