Title (EN) AN ELECTROCHEMICAL PROCESS TO PREPARE CHEMICALS USING A CYANIDE SALT
(FR) PROCESSUS ÉLECTROCHIMIQUE POUR PRÉPARER DES SUBSTANCES CHIMIQUES AU MOYEN D'UN SEL DE CYANURE
Abstract: front page image
(EN)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.
(FR)L'invention concerne un processus mettant en œuvre la réaction d'un cyanure avec un composé réactif de cyanure d'hydrogène, caractérisé en ce que la cyanure est un sel de cyanure et le processus est un processus électrochimique impliquant le transport d'un mélange de réaction auquel le sel de cyanure a été ajouté via une cellule électrochimique. Dans ce processus, le sel de cyanure réagit avec le composé réactif de cyanure d'hydrogène et, tout en étant au moins partiellement sous l'influence d'un courant électrique, le sel de cyanure est acidifié et la teneur en cations de sel est réduite.
