Experimental Data
The solubilities of acetonitrile (1) and 1-dodecanol (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 20.0°C (293.2 K, compilers). The upper critical solution temperature was extracted from the reported graphs by the compilers and found to be 35.7°C (308.9 K).
