Variables:

Room Temp: 25 °C

Prepared by:

M.C. Haulait-Pirson

Method/Apparatus/Procedure:

175 mg (1) were equilibrated with 700 mL (2) in closed flasks by shaking on a constant temperature bath for 12 hours. The flasks were then allowed to stand for 24 hours. Aliquots of 100 mL were removed, filtered through a 0.45 µm Millipore filter, then extracted three times with 10-mL portions of hexane containing an internal standard. The concentration of (1) was determined by injection of the hexane extract into a dual column gas chromatograph equipped with flame ionization detectors.

Source and Purity of Materials:

1. Analabs Inc., 99+%.
2. Doubly distilled.

Estimated Errors:

Ambient temperature: ±0.1°C
Mass concentration (m/v) (1): ±16%
