   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 HCl; purified by vacuum distillation in a Vigreux column; crystallized from 5% solution in ethanol; freezing point=3

Estimated Errors:

   Temperature: ± 0.1.
