Method/Apparatus/Procedure:
Standard 1,1,1-trichloroethane solutions of increasing concentration were prepared in volumetric flasks as described elsewhere.

. 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:
Solubility: ± 5.17 % std. dev.
Temperature: ± 0.5 K (compiler).
