Source Publication

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:
  1. Source not specified; best grade reagent; dried and twice distilled.
  2. 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
