(1) 1,1-Dichloroethene, C₂H₂Cl₂; [75-35-4] NIST WebBook
(2) Water, H₂O; [7732-18-5] NIST WebBook

Original Measurements

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

Variables:

Ambient temperature: 303 K

Prepared by:

A.L. Horvath

Method/Apparatus/Procedure:

Standard 1,1-dichloroethene solutions of increasing concentration were prepared in volumetric flasks as described elsewhere.¹ The aqueous organic liquid phase was 25 cm³ and the vapor phase above the mixture was 35 cm³. The system was allowed to reach equilibrium in a constant temperature bath and then a sample was injected into the gas chromatograph for analysis. Values reported are an average of at least five 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.

Estimated Errors:

Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): ±3.67% std. dev.
