Original Measurements:
Hoerr, C.W.; Harwood, H.J.; Ralston, A.W., J. Org. Chem. 9, 267 (1944).
Variables:
Temperature = 273 K to 309 K
Prepared By:
Valerii P. Sazonov and Nikolai V. Sazonov
Experimental Remarks:
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).
