Method/Apparatus/Procedure:
   A known volume of water was added to dried dichloromethane to prepare a series of standard solutions for establishing calibration curves and obtaining the saturated solutions at each temperature. The determination of the water content of dichloromethane was made  with an RM-250 NMR spectrometer (radiation frequency of 250 MHz). The reported water peak amplitude was the mean of four readings taken at a particular temperature.
