Experimental Values:
Note: The solubilities of acetonitrile (1) and octadecanamine (2) in mass percent including the region of immisciblity over the indicated temperature range were reported in graphical form and in a table. Monotectic equilibrium occurs at 48.2°C (321.4 K, compilers).Mutual solubility of acetonitrile (1) and octadecanamine (2)
