A process for detoxifying of cyanohydrins and / or nitriles 12-40 times higher containing

摘要

the invention concerns a method to detoxify of cyanhydrine, especially glykolnitril and / or nitriles containing aqueous solutionsin addition zersetzungskatalysatoren for peroxidverbindungen, especially manganverbindungen containby the cyanoverbindungen perhydrolyse at temperatures from 5 to c and a ph of 8 to 12,with one or more peroxidverbindungen from the series of alkalipercarbonate and perborates of alkali, alkaline earth and as well as the erdalkaliperoxide,with the above peroxidverbindungen of detoxifying solution as such added or in the detoxifying solution in situ are formed. is preferred natriumpercarbonat used.the erfindungsgemu00e4u00dfe $a procedure is effective and economic as the vorbekannte using hydrogen peroxide.
