Methodology:
A mixture of 1 to 15 volume ratio of heavy water and pentachloroethane 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.
