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 dodecanoic acid at 190°C to 210°C for 10 hours to 14 hours; purified by recrystallization; freezing point = 102.4°C.
Estimated Errors:
Ambient temperature: ±0.2 K.
