 Method/Apparatus/Procedure:
   Measurements were carried out in a 100 mL stainless-steel cell. The cell was loaded with 15 g (2) and brought to temperature. Mixing was started anf (1) wa injected until either a cloud or a small droplet of a second phase appeared at the top of the cell. Then mercury was injected to change pressure, more (1) was injected and the measurement was repeated.

 Source and Purity of Materials:
   (1) Phillips reagent grade; better than 99.8%; used as received.
   (2) distilled and dearated.

 Estimated Errors:

   Temperature: ± 0.02 K
   Pressure: ± 2 atm.
