 Method/Apparatus/Procedure:
   Alexejev's synthetic solubility determination method was used (ref. 1). A fixed weight of dichloromethane and water was sealed in a tube and the mixture was subjected to gradually increasing temperature with constant agitation. The appearance of opalescence or clouding  was the indication of the saturation temperature. The temperature was then allowed to fall and an observation made, while the tube was constantly agitated, of the temperature of the first appearance of opalescence. The observation was repeated  several times.
