Variables:

Ambient temperature: 205 - 338 K

Prepared by:

V.P. Sazonov

Method/Apparatus/Procedure:

The synthetic method was used. Samples of (1) and (2) of weight about 0.2 g were placed in glass ampoules of length 3 to 4 cm and inner diameter of 4 mm. After cooling in a mixture of ice with salt ampoules were sealed. Three to four ampoules were attached to a thermometer and placed in a glass bath with glycerine (for heating) or with acetone and solid CO₂ (for cooling) with continuous stirring. The heating and cooling 2 K per minute. The UCST was determined by following the appearance and disappearance of the meniscus.

Source and Purity of Materials:

1. Source not specified; purity not specified; dried and purified; boiling point = 81.6°C, n(20°C, D) = 1.3458.
2. Synthesized in Institute of Chemistry (Upha, Russia).

Estimated Errors:

Ambient temperature: ±0.1 K (243 K to 373 K); ±0.5 K (below 243 K).
