Abstract

Procédé pour la fabrication de cyanure de benzoyle à partir de chlorure de benzoyle et de cyanure de métal alcalin. Caractérisé en ce que la réaction s'effectue dans un solvant organique inerte en présence d'anhydride d'acide benzoïque ou de substances qui forment avec le chlorure de benzoyle, de l'anhydride d'acide benzoïque. Procédé applicable pour un rendement élevé.A process for the production of benzoyl cyanide from benzoyl chloride and alkali metal cyanide. Characterized in that the reaction is carried out in an inert organic solvent in the presence of benzoic acid anhydride or of substances which form with benzoyl chloride, benzoic acid anhydride. Applicable process for high efficiency.
