Methodology:
A 1 to 15 volume ratio mixture of heavy water and diiodomethane was introduced into an equilibration flask and then lowered into a water thermostat bath. 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. The description was taken from a secondary source [1]. The original report is no longer available.
