Method/Apparatus/Procedure:
Analytical balance and constant temperature bath.
Mixtures of known composition were sealed in glass ampoules, and placed in a constant temperature bath. Ampoules were slowly rotated at about 0.25 rps, while the bath temperature was increased by 0.1 K every 1,200 seconds. Temperature at which the last trace of solid disappeared was visually determined.
Source and Purity of Materials:
(1) 98.67 % minimum, Eastern Kodak Company, USA, was purified by column chromatography and recrystallized from toluene before use.
(2) Gold Label, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was used as received.
