Original Measurements

Ralston, A. W.; Hoerr, C. W.; Pool, W. O.; J. Org. Chem. 8, 473-88 (1943).

Variables:

Room Temp: 283 - 355 $\pu{K}$

Prepared by:

N.V. Sazonov, V.P. Sazonov

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:
  1. Source not specified; best grade reagent; dried and twice distilled.
  2. Prepared by passing of ammonia through octanoic acid at 190°C to 210°C for 10 to 14 hrs; purified by recrystallization; FP = 105.9°C.
Estimated Errors:

Ambient temperature: ±0.2 K.
