The solvent was degassed by alternately opening to the vacuum pump for 5-15 s and then stirring very rapidly to produce cavitation. This was repeated 5-10 times. In the solubility measurement itself gas, which had been previously saturated with solvent vapor, was admitted to the saturation vessel, holding about 80 mL of solution, and with 5-10 mL remaining space, volume-time measurements were taken and extrapolated back to the time the gas was admitted. Then the stirrer was turned on and driven very fast, producing a slightly (~1%) supersaturated solution. The approach to equilibrium was then followed from each direction while stirring as rapidly as possible without producing cavitation and bubbles.", "reference": {"citation": "Eucken, A.; Herzberg, C.; Z.
