Original Measurements
Connolly, J. F.; J. Chem. Eng. Data 1966, 11, 13-6.
Variables:
Ambient temperature: 280 - 310 °C
Pressure: 150 - 600 atm
Prepared by:
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:
- Phillips reagent grade; better than 99.8%; used as received.
- distilled and dearated.
Estimated Errors:
Ambient temperature: ±0.02 K
Pressure: ±2 atm.
