Method/Apparatus/Procedure:
   The synthetic method (Alekseev¹) was used. The temperatures of phase transitions were determined both on heating and cooling of the mixtures and the average of the values of temperature obtained were taken. Measurements were carried out in thermostat with silicone at temperatures above 80 °C.

Source and Purity of Materials:
   (1) Source not specified; pure grade reagent; dried and twice distilled on a laboratory packed column; purity 99.9 mole %.
   (2) Source not specified; pure grade reagent; dried and repeatedly distilled under vacuum; purity 99.5 mole %.
   (3) Source not specified; pure grade reagent; dried and repeatedly distilled under vacuum; purity 99.5 mole %.
   (4) Twice distilled.

Estimated Errors:

   Temperature: Not specified.
