Method/Apparatus/Procedure:
   The solubility versus temperature measurements were made by the so called synethetic method which involved the mixing of known masses of solute and solvent and the testing of miscibility with temperature. A bracketing procedure was applied in this method, two adjustable thermostats, one above and the other below the solubility temperature, were used. The contents of sample tubes in the two thermostat baths were observed to maintain one homogeneous and the other heterogeneous as the temperature interval between the two thermostats were reduced by successive steps.

Source and Purity of Materials:
   (1) Synthesized by the chlorination of phenol in carbon tetrachloride, purified as described in Ref. 1, no criterions of the purity given.
   (2) Source and purity not specified.
