Method/Apparatus/Procedure:
250 ml bottles were filled with distilled deionized water and sealed. Measured volumes of trichlorofluoromethane were injected into the bottles through each bottle septum using a microliter syringe. The solute was in excess of the anticipated solubility limit. The bottles were shaken for 1 hour with a wrist-action shaker and allowed to equilibrate for about 3 weeks. Samples were then injected into a gas chromatograph equipped with a Carbopack column and a FID detector. The GC responses were compared with a calibration plot to establish concentrations.
Source and Purity of Materials:
(1) Probably a commercial reagent, at least 99 % purity, used as received.
(2) Distilled deionized.
Estimated Errors:
Solubility: Not specified.
Temperature: ± 0.5 K (compiler).
