Ferloni, P.; Riccardi, R.; Int. Data Series: Sel. Data Mixtures, Ser. A(2), 84-90 (1977).

Variables:

Room Temp: 371 - 385 $\pu{K}$

Prepared by:

V.P. Sazonov

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 $\ce{Pt}$ 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 $\ce{P2O5}$ filled tube.
  2. Fluka AG; purity 99 mole%; purification as above.
Estimated Errors:

Ambient temperature: reproduced better than 0.1 K.
