Conditions:
Room Temp:
20 - 284
°C
Mass per 100 g water (2):
[NaCl]
g1/100 g2

Methodology:
At higher temperatures: (1) and the aqueous brine were placed in an autoclave, described in detail in the paper, and equilibrated by stirring. After settling, the solubility of (3) in (1) was determined volumetrically by withdrawing layers from the autoclave into a burette. At lower temperatures: (1) and the aqueous solution were refluxed in a flask at constant temperature. After equilibration, an aliquot of the water rich layer was withdrawn and analysed argentometrically and the solubility of (3) in (1) calculated. The solubility of $\ce{NaCl}$ in benzene was determined to be negligible in these experiments ($\pu{8E-5 mol/L}$ at 223 °C and 54.23 atm).
