Abstract: 1,262,172. Separating cyanogen chloride and hydrogen chloride. AGRIPAT S.A. 7 Aug., 1969 [8 Aug., 1968], No. 39516/69. Heading B1L. The components of a gaseous mixture comprising cyanogen chloride, hydrogen chloride, and possibly chlorine, produced in reactor 13 by the reaction between hydrogen cyanide and chlorine, are separated by countercurrent absorption of the hydrogen chloride and some of the cyanogen chloride in water in absorber 16, gaseous overhead of chlorine and the bulk of the cyanogen chloride leaving by line 17, suitably for use in the production of cyanuric chloride. The absorption is preferably performed at 15-25C with a contact time of 0.3-3 seconds. The bottoms are passed to stripper 21 where the dissolved cyanogen chloride is stripped by a rising countercurrent stream of air, or more preferably chlorine, which enters by line 19, the overhead being then passed back to reactor 13 by line 22. The liquid bottoms pass by line 23 to reboiler 24, hydrochloric acid being recovered therefrom by line 26 and residual chlorine being returned to stripper by lines 25, 19.
