---

Components:
   (1) 1-Decanol; C10H22O; [112-30-1]  NIST Chemistry WebBook for detail
   (2) Acetonitrile; C2H3N; [75-05-8]  NIST Chemistry WebBook for detail

Original Measurements:
   Hoerr, C.W.; Harwood, H.J.; Ralston, A.W., J. Org. Chem. 9, 267 (1944).

Variables:
   Temperature = 269 K to 295 K

Prepared By:
   Valerii P. Sazonov and Nikolai V. Sazonov

Experimental Remarks:

   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).
