Method/Apparatus/Procedure:
The saturation of dichloromethane and water mixtures occurred in a flask fitted with a thermostat jacket and a powerful stirrer. After a stirring time of 10 - 20 minutes, samples were withdrawn from both the organic and aqueous layers and the compositions were determi ned from their refractivity indices.
