These data are extracted by compilers from the published graphs.
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.

Source and Purity of Materials:
(1) Source not specified; best grade reagent; dried and twice distilled.
(2) Prepared by passing of ammonia through the octanoic acid at 190-210 °C for 10 to 14 hours; purified by recrystallization; f. p. = 98.5 °C.
Estimated Errors:
Temperature: control to ±0.2 K
