Method/Apparatus/Procedure:
The synthetic method (Alekseev
1
) was used. Mixtures of (1), (2) and (3) of mass 10 g were heated with vigorous stirring to a temperature higher than the homogenization temperature, and then slowly cooled until turbidity appeared. Heating and cooling cycles were repeated twice. Temperature values obtained for appearing and disappearing turbidity were averaged.
Source and Purity of Materials:
(1) Source not specified; pure grade reagent; dried and twice distilled in a glass packed column.
(2) Source not specified; pure grade reagent; dried and twice distilled in a glass packed column.
(3) Analytical purity; dried and twice distilled under vacuum; 0.03 mass % water by the Karl Fischer analysis.
Estimated Errors:
Temperature: ± 0.01 K.
