Method/Apparatus/Procedure:
   The dynamic method used for the solubility determination consisted of the saturation of nitrogen with 1,2-dichloroethane vapor which was then bubbled through a thermostatically controlled flask filled with a definite volume of water. After 2-3  hours the solution became saturated and samples were taken periodically.¹ The concentration of the 1,2-dichloroethane in the solution was determined by GLC. Some 3-5 measurements were taken at each temperature.

   (3) Distilled (compiler).

Estimated Errors:
   Solubility: ± 15 %.
   Temperature: ± 0.05 K.
