A method has been developed for the determination of fluorine and chlorine in chlorine trifluoride. Chlorine trifluoride vapor is passed through a known weight of dry sodium chloride, contained in a copper tube. Sodium fluoride is produced and the free chlorine which is liberated is absorbed in sodium hydroxide solution. After decomposition of the sample, chlorine and fluorine are determined in the sodium chloride/fluoride mixture and in the sodium hydroxide solution. From the known weight of sodium chloride used the chloride contributed by the sample can be calculated. The chloride is determined by Mohr's method and the fluoride is titrated with thorium nitrate using alizarin red as indicator. (auth)
