Original Measurements
Riccardi, R.; Franzosini, P.; Rolla, M.; Z. Naturforsch. A 23, 1816-8 (1968).
Variables:
Ambient temperature: 344 - 356 K

Method/Apparatus/Procedure:
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:
- Fluka AG; purity 99 mole%; fractionally distilled, degassed and finally distilled through a P2O5 filled tube.
- Fluka AG; purity 99 mole%; purification as above.
Estimated Errors:
Ambient temperature: reproduced better than 0.1 K.
