Methodology:
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 $\ce{Pt}$ resistance thermometers, which were checked against standards. Phase changes (cloud points) were observed as mixtures were cooled.
Sample Information:
- Fluka AG; purity 99 mole%; fractionally distilled, degassed and finally distilled through a $\ce{P2O5}$ filled tube.
- Fluka AG; purity 99 mole%; purification as above.
Measurement Errors:
Ambient temperature: reproduced better than 0.1 K.
