bottles were filled with distilled and deionized water and sealed. Measured volumes of 1,1,2-trichloro-1,2,2-trifluoroethane 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 three weeks. Samples were then injected into a gas chromatograph equipped with a Carbopack column and a FID detector. The gas chromatography (GC) responses were compared with calibration response plots to establish concentrations.
Source and Purity of Materials:
(1) Probably a commercial reagent at least 99 % purity; used as received.
(2) Distilled and deionized.
Estimated Errors:
Solubility: Not specified.
Temperature: ± 0.5 K (compiler).
