T/KMole Fraction x1Mole Fraction x2
311.30.10560.8944
318.90.13930.8607
325.80.18590.8141
333.90.26280.7372
 Method/Apparatus/Procedure:
   Constant temperature bath and a precision thermometer. Mixtures of known concentrations sealed in glass ampoules and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility  determined by noting the temperature at which the last trace of solid solute disappeared.

 Source and Purity of Materials:
   (1) 99.5 %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was recrystallized from solution.
   (2) 99+ %, Aldrich Chemical Company, having isomer ratio of 60.6 % cis and 39.4 % trans, stored over molecular sieves.

 Estimated Errors:
   Solubility: x1: ± 0.0003.
   Temperature: T/K: precision ± 0.1.
