Ralston, A. W.; Hoerr, C. W.; Pool, W. O.; Harwood, H. J.; J. Org. Chem. 9, 102-112 (1944).

Conditions:

Room Temp: 303 - 349 $\pu{K}$

Compilers:

N.V. Sazonov, V.P. Sazonov

Methodology:

The solubility measurements were made with the equipment and in the manner previously described elsewhere [1,2].

Sample Information:
  1. Source not specified; purity not specified; freshly distilled and cooled without access to the atmosphere, to prevent contamination with carbon dioxide.
  2. Prepared by hydrogenation of the highly purified nitrile as in work [1]; purified by two vacuum distillations; FP = 53.06°C
Measurement Errors:

Ambient temperature: Not specified.
Mass concentration (m/v) (1): Not specified

System Components:
  1. Acetonitrile, $\ce{ C2H3N }$; [75-05-8] NIST WebBook
  2. Octadecanamine, $\ce{ C18H39N }$; [124-30-1] NIST WebBook
Experimental Data

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).
