1421876 Detoxification of cyanides JENAPHARM VEB 30 April 1974 [10 May 1973] 18829/74 Heading C1C A process for the detoxification of cyanides or cyanide-containing solutions is described wherein the solution is pre-heated by heat exchange, fed to a tubular reactor with a laminar pressure flow, and the hydrolysis of the cyanide initiated by a temperature shock at 200-250‹ C., 40- 150 atm. The temperature shock may be produced by heat of reaction (e.g. by adding cone. sulphuric acid) or very sudden heating. A device for carrying out the process is also described.
