Conditions:

Room Temp: 283 - 333 $\pu{K}$

Compiler:

V.P. Sazonov

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:
  1. Source not specified; best grade reagent; dried and twice distilled.
  2. 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:
  1. Acetonitrile, $\ce{ C2H3N }$; [75-05-8] NIST WebBook
  2. 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).
