Methodology:
The synthetic method was used. The solubilities of (2) in (1) were determined in sealed tubes by the method and apparatus described elsewhere [1,2].
Sample Information:
- Source not specified; best grade reagent; dried and twice distilled.
- Obtained from the ketoesters by hydrolyzing with 5% alcoholic potassium hydroxide; purified by several crystallizations from ethanol; FP = 77.2°C.
Measurement Errors:
Ambient temperature: ±0.2 K.

System Components:
- Acetonitrile, $\ce{ C2H3N }$; [75-05-8] NIST WebBook
- 14-Heptacosanone, $\ce{ C27H54O }$; [542-50-7] NIST WebBook
Experimental Data
The solubilities of 14-heptacosanone (2) in acetonitrile (1) in mass percent including the region of immisciblity over the indicated temperature range were reported in graphical form and in a table. Monotectic equilibrium is realized at 71.8°C (345.0 K, compiler). The upper critical solution temperature was reported to be above 82°C.
