Ralston, A. W.; Hoerr, C. W.; Pool, W. O.; J. Org. Chem. 8, 473-88 (1943).
Conditions:
Room Temp: 283 - 334 $\pu{K}$
Compilers:
N.I. Lisov, N.V. Sazonov, V.P. Sazonov
Methodology:
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].
Sample Information:
- Source not specified; best grade reagent; dried and twice distilled.
- Prepared by heating the hexadecanoyl chloride with diphenylamine for two to four hours at 135-145°C; purified by recrystallization; FP = 69.5°C.
Measurement Errors:
Ambient temperature: control ±0.2 K
