Method/Apparatus/Procedure:
   A mixture of 1 to 15 volume ratio of heavy water and 1,2-dichloropropane was introduced into an equilibration flask and then lowered into a waterbath thermostat. The assembly was shaken mechanically for about 90 minutes at constant temperature. The  amount of heavy water in the organic phase was determined by a modified Karl Fischer titration method. The determination was done in triplicate. This procedure description was  taken from a secondary source.1 The original university report is no longer available.
