Original Measurements

Nelson, H. D.; De Ligny, C. L.; Recl. Trav. Chim. Pays-Bas 1968, 87, 528-44.

Variables:

Ambient temperature: 5 - 45 °C

Prepared by:

M.C. Haulait-Pirson

Method/Apparatus/Procedure:

The saturation vessel is drawn in the original paper. (2) was saturated with (1) via the vapor phase: a few drops of (1) were put on the bottom of a tight-fitting flask containing a small 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.

Estimated Errors:

Mass concentration (m/v) (1): error given above (standard deviation)
