Solubility of hexane in water
t/°C106 * Mole Fraction x1
4.03.42 ± 0.34
14.03.17 ± 0.52
25.018.33.83 ± 0.47
35.02.69 ± 0.26
45.022.24.64 ± 0.72
55.021.24.42 ± 0.26
Method/Apparatus/Procedure:
   The saturation vessel is drawn in the original paper. (2) was saturated with (10 via the vapor phase: a few drops of a tight-fitting flask filled with water. Complete saturation was reached by shaking overnight in an upright position. Samples were taken from the aqueous solution with a microsyringe through the septum and injected into the gas chromatograph equipped with a flame ionization detector. The gas chromatographic conditions are described in the paper.

Source and Purity of Materials:
   (1) Fluka purum.
   (2) tap-water was refluxed for 8 hours in the presence of Kmno4 and KOH and distilled. The whole process was repeated once more.
