Notes:
Authors report eutectic point occurs at x
1
= 0.063 and T/K = 275.3.
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 temperature at which the last trace of solid solute disappeared.
Source and Purity of Materials:
(1) 99 %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was recrystallized from toluene.
(2) 99+ %, Aldrich Chemical Company, was fractionally distilled and stored over molecular sieves.
