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 heating the hexadecanoyl chloride with diphenylamine for two to four hours at 135°C to 145°C; purified by recrystallization; FP = 69.5°C
Estimated Errors:
Ambient temperature: ±0.2 K.
