 Method/Apparatus/Procedure:
   Constant temperature bath, analytical balance and high pressure equipment.
Excess solute and solvent allowed to equilibrate in a specially designed high pressure cell at constant temperature for 20-24 hours. Known amount of saturated solution removed, solvent evaporated to dryness, and concentration determined from weight of solid residue.

 Source and Purity of Materials:
   (1) Purest grade, Eastman Kodak Chemical Company, Rochester, New York, USA, was used as received.
   (2) Pure grade, Phillips Petroleum, was dried over phosphorous pentoxide and distilled.

 Estimated Errors:

   Temperature: T/K: ± precision 0.1. x1: ± 1-3 % at atmospheric pressure, and ± 10 % at the higher pressures.
