Abstract
1487987 Chlorine production from carbon tetrachloride HOECHST AG 24 Feb 1975 [22 Feb 1974] 7620/75 Heading ClA [Also in Division C2] Chlorine is produced by the pyrolysis of COl 4 , optionally in admixture with one or more other chloro - carbon compounds, at 750- 950‹ C. and a pressure of 0À1-5 bars, at a rate of 1-50 kg. per litre of reaction volume per hour in contact with substantially graphitic C which is heated by a passage of an electric current therethrough, rapidly cooling the resulting mixture and separating Cl 2 from the Cl 2 C=CCl 2 in the cooled mixture. The chlorine may be obtained in liquid or gaseous form.
