Notes:
Compiler: Eutectic point occurs at about x

= 0.385 and T/K = 305.7.
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) Highest Purity, Eastman Chemicals, was recrystallized.
(2) Highest Purity, Eastman Chemicals, was recrystallized.
