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 in Ralston et al.1 and Hoerr and Ralston.2

Source and Purity of Materials:

(1) Source not specified; best grade reagent; dried and twice distilled.
(2) Obtained by heating of hexadecanoic acid with redistilled aniline at (150 to 170)°C for 2 to 3 hours; purified by recrystallization; f. p. = 90.2°C.

Estimated Errors

Temperature: control ±0.2 K
