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.
- 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.
