Experimental Data

The solubilities of acetonitrile (1) and 1-decanol (2) in mass percent including the region of immisciblity over the indicated temperature range were reported in graphical and tabular form. Monotectic equilibrium occurs at 5.1°C (278.3 K, compilers). The upper critical solution temperature was extracted by the compilers to be 22.2°C (295.6 K).
