Conditions:
Room Temp: 283 - 333 $\pu{K}$
Compiler:
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 the latter with 5% alcoholic potassium hydroxide; purified by several recrystallization from ethanol; FP = 57.8°C
Measurement Errors:
Ambient temperature: ±0.2 K.

System Components:
- Acetonitrile, $\ce{ C2H3N }$; [75-05-8] NIST WebBook
- 10-Nonadecanone, $\ce{ C19H38O }$; [504-57-4] NIST WebBook
Experimental Data
The solubilities of 10-nonadecanone (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 49.3°C (322.5 K, compiler). The upper critical solution temperature was extracted from the reported graphs by the compiler and found to be 60.4°C (333.6 K).
