Method/Apparatus/Procedure:
The water-rich mixture was studied using gas-liquid chromatography in which a mixture of methane and 1,1-dichloroethane vapor passed through the sampling loop. The eluted 1,1-dichloroethane was determined with a flame ionization detector. The organic-rich mixture was studied using an isopiestic method in which $\ce{CaCl2}$ solution controlled the partial pressure of water. The water concentration of the sample was determined using a Karl Fischer titration apparatus.
Source and Purity of Materials:
- Fluochem Limited. Redistilled in a glass sieve tray column.
- Double distilled tap water.
Estimated Errors:
Ambient temperature: ±0.05 K.
Mass concentration (m/v) (1): Not specified.

Experimental Data
Mole fraction of 1,1-dichloroethane (x1) was calculated from the activity coefficients at infinite dilution (γ∞1) using the relation x1 = 1/γ∞1.
