 Method/Apparatus/Procedure:
   The synthetic method was used. Solutions of (1) and (2) were sealed in 5 mL glass vials. Cloud points were observed visually in an acetone bath slowly cooled by addition of dry ice. Temperatures were taken on an alcohol thermometer.

 Source and Purity of Materials:
   (1) Fisher; reagent grade; distilled at 60 °C at 24.4 kPa.
   (2) Phillips; research grade; purity 99.89 mole %.

 Estimated Errors:

   Temperature: ± 3 K.
