Original Measurements

DuBrow, P. L.; Hoerr, C. W.; Harwood, H. J.; J. Am. Chem. Soc. 74, 6241-5 (1952).

Variables:

Room Temp: 313 and 323 $\pu{K}$

Prepared by:

V.P. Sazonov

Method/Apparatus/Procedure:

The synthetic method was used. The solubilities were determined by observing visually the temperatures at which known concentrations precipitated upon cooling and dissolved upon heating.

Source and Purity of Materials:

1. Source not specified; reagent grade; freshly distilled.
2. Prepared by the reaction of highly purified stearic acid with 2-aminobenzenethiol at elevated temperatures, using catalytic amounts of $\ce{HCl}$; purified by vacuum distillation in a Vigreux column; crystallized from 5% solution in ethanol; FP = 39.60°C.

Estimated Errors:

Ambient temperature: ±0.1.
