Method/Apparatus/Procedure:
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].
Source and Purity of Materials:
- Source not specified; best grade reagent; dried and twice distilled.
- Obtained from the ketoesters by hydrolyzing with 5% alcoholic potassium hydroxide; purified by several recrystallizations from ethanol; FP = 69.3°C.
Estimated Errors:
Ambient temperature: ±0.2 K.

Experimental Data
The solubilities of 12-tricosanone (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 62.3°C (335.5 K, compiler). The upper critical solution temperature was reported to be above 82°C.
