   Valerii P. Sazonov and Nikolai V. Sazonov

Experimental Remarks:

   The solubilities of acetonitrile (1) and 1-hexadecanol (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 44.5 °C (317.7 K, compilers). The upper critical solution temperature was extracted from the reported graphs by the compilers and found to be 57.5 °C (330.7 K).
