Notes:
   1  Gas-liquid chromatographic parameter, from instrument calibration.

Method/Apparatus/Procedure:
   Gas-liquid chromatography was used for the determination of the partition of dichloromethane with thin layers of water coated on Porasil D. Helium carrier gas was presaturated with water at the column temperature. The eluents were detected with an F & M flame ionization detector.  The partition coefficient was obtained from the slope of the straight line plot of VN/AL versus VL/AL.
