Method/Apparatus/Procedure:
   Temperatures were maintained using a thermostat bath with continious stirring. Partial pressures of chlorobenzene were determined over 2 liter aqueous solutions in a flask. The equilibrium chlorobenzene content of the vapor was calculated from the gas laws. The amount of water vapor was obtained from the total weight increase of the absorber less the weight of the chlorobenzene absorbed. The chlorobenzene vapor pressure was directaly proportional to its content in water. Duplicate measurements were made at each temperature.

Source and Purity of Materials:
   (1) Source not specified, n²⁰_D=1.5248 b.p. = 132°C
   (2) Redistilled before use.

Estimated Errors:
   Solubility: ±4%.
   Temperature: ±0.1 K.
