Method/Apparatus/Procedure:
250 mL 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 one 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:
- Probably a commercial reagent at least 99% purity; used as received.
- Distilled and deionized.
Estimated Errors:
Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): Not specified.
Components:
- 1,1,2-Trichloro-1,2,2-trifluoroethane, $\ce{ C2Cl3F3 }$; [76-13-1] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
