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) Eastman; practical grade; dried over CaSO
4
and distilled once from CaH
2
and second time from over sodium at 79 °C/5.6 kPa.
Estimated Errors:
Temperature: ± 3 K.
