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 in Ralston et al.1 and Hoerr and Ralston.2

Source and Purity of Materials:
   (1) Source not specified; best grade reagent; dried and twice distilled.
   (2) Prepared by passing of ammonia through the octanoic acid at 190-210 °C for 10 to 14 hours; purified by recrystallization; f. p. = 98.5 °C.

Estimated Errors:

   Temperature: control to ±0.2 K
