 Method/Apparatus/Procedure:
   Turbidimetric titrations were used for both the aqueous and the organic phases. First, trichloromethane was titrated with water from a microburet until the appearance of turbidity. Then, water was titrated with trichloromethane. The amount of trichloromethane  or water in the flask was weighted to an accuracy of 0.01 g. The temperature was maintained constant by using ultrathermostat bath. The trichloromethane-water-caprolactam ternary system was also studied.
