The reaction of Gold with chlorine or bromine in molten alkali halides was studied over a range of temperatures and halogen partial pressures. Equilibrium concentration of AuI and AuIII were determined by chemical analysis of samples taken at temperatures of 350 to 1050C. The equilibrium constants decreased with increasing temperature. This system is considered for use in removing chlorine and bromine from halogenated hydrocarbons in the atmosphere of a submarine since gold has a much higher affinity for chlorine at 100C than at 500C. The lowest practical temperature of operation is 350C due to freezing of the salt mixture. At this temperature pure silver wool would be much more effective in removing the chlorine and bromine but could not be regenerated in place. Author
