Method/Apparatus/Procedure:
The method involved repeated equilibrations of nitrogen with a liquid water sample containing the trichlorofluoromethane. Each sample was shaken vigorously at the required temperature in a constant temperature bath for 30 minutes. The equilibrated gas phase was then injected into a gas chromatograph. The experiments were performed at least three times at 10, 15, 20, and 25
o
C; each experiment involved about six equilibrations.
