Method/Apparatus/Procedure:
The synthetic (Alekseev) method was used. Sealed samples, about 1.0 - 1.5 g, of various compositions were heated to a temperature higher than that required for complete homogeneity, then cooled at about 0.01 K·min
-1
until turbidity and a meniscus appeared. Repeat determinations were made.
Source and Purity of Materials:
(1) Source not specified; purity not specified; dried and twice distilled.
(2) Isolated from a Fischer-Tropsch gasoline fraction freed from unsaturated hydrocarbons; fractionally distilled.
Estimated Errors:
Solubility: Not specified.
Temperature: Not specified.
