   a  Reported (mean values from at least two measurements).
   b  Calculated by F. W. Getzen.
   c  The system reported not stable at this temperature.

   The equilibrations were done over periods from 2 to 17 days (average 7-10 days). Gravimetric analysis was the basis for the concentration determinations. The solute was placed in a spiral tube and weighed. Then, a known amount of water was passed through the tube and it was re-weighed. The weight loss and the mass of the water passed through the tube gave the solubility value directly.

Source and Purity of Materials:
   (1) Synthesized from benzene and chlorine, recrystallized from abs. Ethanol, m.p. 53°C. The purity of the product was checked by elemental analysis.
   (2) Source and purity not specified.

Estimated Errors:
   Solubility: >10% (evaluated on the basis of deviations from the averages).
   Temperature: ± 0.5 K.
