Method/Apparatus/Procedure:
The equilibration between 1,1,2,2-tetrabromoethane and water was established in a flask with a stirrer. The entire apparatus was immersed in a thermostat. After equilibrium was established, samples of the mixture were taken for an x-ray spectroscopic determination of bromine and a gas chromatograph analysis using a flame ionization detector. The values presented are averages from duplicate experiments at each temperature. The determination was also reported in a Ph. D. thesis.
