Method/Apparatus/Procedure:
The dynamic method was used for the determination of the solubility. 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 solution. After 2-3 hours the solution became saturated and samples were taken periodically (ref. 1). The concentration of dichloromethane in the solution was determined by GLC. On average, 3 - 5 measurements were taken at each temperature.
