Method/Apparatus/Procedure:
An excess of trichloromethane in 500 g water was shaken for 12 hours in a thermostat bath. Samples were then withdrawn and read against water in the interferometer made by Zeiss (ref. 1).A detailed description of the complete procedure is given in a Ph. D. thesis (ref.2).
