Original Measurements:
Walraevens, R.; Trouillet, P.; Devos, A., Int. J. Chem. Kinet. 6, 777-86 (1974)
Variables:
Temperature = 283 K - 353 K
Prepared By:
A. L. Horvath
Experimental Remarks:
The temperature dependence of the solubility of 1,1,2,2-tetrachloroethane in water versus absolute temperature was expressed by the equation:
log

(
S
/mol dm

)=2070/(
T
/K) - 15.316+0.0222(

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

Method/Apparatus/Procedure:
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.
Source and Purity of Materials:
(1) Solvay chemical, rectified before use, purity was 99.9 % by GLC analysis.
(2) Distilled.
Estimated Errors:
Solubility: Not specified.
Temperature: ± 0.5 K.
