Method/Apparatus/Procedure:
The synthetic method
1
was used. Tubes were filled under vacuum with known masses of degassed and moisture-free components, sealed, and then placed in a thermostat bath filled with paraffin oil. The mixtures in the tubes were shaken by a Chemap vibromixer type E-1. Temperatures were measured with Degussa Pt resistance thermometers, which were checked against standards. Phase changes (cloud points) were observed as mixtures were cooled.
Source and Purity of Materials:
(1) Fluka AG; purity 99 mole %; fractionally distilled, degassed and finally distilled through a P

filled tube.
(2) Fluka AG; purity 99 mole %; purification as above.
Estimated Errors:
Temperature: reproduced better than 0.1 K.
