Original Measurements

McNally, M. E.; Grob, R. L.; J. Chromatogr. A 1984, 284, 105-16.

Variables:

Room Temp: 303 $\pu{K}$

Prepared by:

A.L. Horvath

Method/Apparatus/Procedure:

Standard 1,1,1-trichloroethane solutions of increasing concentration were prepared in volumetric flasks as described elsewhere [1]. The aqueous organic liquid phase was 25 mL and the vapor phase above the mixture was 35 mL. The system was allowed equilibrium in a constant temperature bath and then a sample was injected into the gas chromatograph. Values reported are an average of at least 5 measurements.

Source and Purity of Materials:

1. Chemical Service, West Chester, PA., USA., purest grade available.
2. Distilled and run through two Barnstead purification cartridges before use.

Estimated Errors:

Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): ±5.17% std. dev.
