   The synthetic method1 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 P2O5 filled tube.
   (2) Fluka AG; purity 99.91 mole %; purification as above.

Estimated Errors:

   Temperature: reproduced better than 0.1 K.
