Method/Apparatus/Procedure:
The synthetic method was used. Sealed ampoules were placed in a glass-walled thermostat. The temperature of the thermostat was increased gradually with periodic stirring and a preliminary determination of the clear-point temperature in every ampoule was made. A more precise value of the cloud-point temperature was determined by allowing the thermostat to cool. The determination was repeated several times.
Source and Purity of Materials:
- Source not specified; pure grade product; distilled over anhydrous soda, boiling point = 81.6°C, n(20°C, D) = 1.3441, p(25°C) = 777 g L-1.
- Source not specified; for chromatography; not purified; boiling point = 68.8°C, n(20°C, D) = 1.3752, p(20°C) = 660 g L-1.
Estimated Errors:
Ambient temperature: ±0.2 K.
