Samples of the saturated aqueous solutions were withdrawn with pipettes through glass-wool plugs and transferred to separatory funnels for weighing. An extraction with cyclohexane was then performed after which the extracts were analyzed spectrophotometrically at 273 nm. The concentrations were established from previously obtained absorbance values of standard reference solutions (which were observed to obey Beer's law).", "dataset": [{"series": 1, "points": [{"pntnum": 1, "conditions": [{"property": "Ambient temperature", "number": "2.22e+01", "significand": "2.22", "exponent": "1", "sigfigs": "3", "unit": "°C"}], "data": [{"property": "Mole fraction -
