Method/Apparatus/Procedure:
A dynamic method was used for the solubility determination. It consisted of the saturation of nitrogen with dichloromethane 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 (ref. 1). The concentration of dichloromethane in water was determined by gas-liquid chromatography. On average, 3 - 5 measurements were taken at each temperature.
