Abstract

a. L'invention concerne un perfectionnement apporté à la synthèse connue, du phénylmalonodinitrile par reaction du phénylacétonitrile sur le chlorure de cyanogène en phase gazeuse. b. Ce perfectionnement se caractérise en ce que les substances de départ sont introduites séparément l'une de l'autre dans le réacteur, sous forme gazeuse. c. Dans ce procédé, la synthèse peut être utilisée d'une manière générale pour la fabrication de malodinitriles substitués par un radical aromatique ou hétéroaromatique.
