Abstract
The present invention relates to a process comprising the reaction of a cyanide with a hydrogen cyanide-reactive compound, characterized in that the cyanide is a cyanide salt and the process is an electrochemical process involving the transporting of a reaction mixture to which cyanide salt has been added through an electrochemical cell, in which process the cyanide salt reacts with the hydrogen cyanide-reactive compound while at least partly under the influence of an electric current the cyanide salt is acidified and the salt cation content is reduced.
