Original Measurements:
   Walraevens, R.; Trouillet, P.; Devos, A., Int. J. Chem. Kinet. 6, 777-86 (1974)

   Temperature = 283 K - 353 K

Experimental Remarks:

   The temperature dependence of the solubility of 1,1,2,2-tetrachloroethane in water versus absolute temperature was expressed by the equation:

log10 (S/mol dm-3)=2070/(T/K) - 15.316+0.0222(T/K), where S=Solubility, and T=absolute temperature.
The temperature interval covered by the above equation is from 283 to 353 K. For example, the calculated solubility derived from the above equation is 2.95×10-1 [100 w1] at 298.15 K (compiler).

Experimental Data:   (Notes on the Nomenclature)
   A mixture of 1,1,2,2-tetrachloroethane and water was preheated to the desired temperature before rapid mixing. The resulting mixture was thermostated and the equilibrium was maintained by vigorous stirring. The concentration of  1,1,2,2-tetrachloroethane in water was determined by gas chromatography.
