Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer.
Mixtures of known concentrations sealed in glass ampoules and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility determined by visual noting the same temperature at which the last trace of solid solute disappeared.
Source and Purity of Materials:
(1) 97.9%, Eastern Chemical Company, Smithtown, New York, USA, was passed over activated alumina and recrystallized from toluene.
(2) Gold Label, 99.9+ %, Aldrich Chemical Company, was used as received.
