Abstract

Procédé pour la préparation de nitrosobenzène. Ce procédé, basé sur la réduction du nitrobenzène, est caractérisé par le fait qu'on utilise comme agent réducteur un hydrocarbure aliphatique, cycloaliphatique, oléfinique ou aromatique, avec des catalyseurs constitués par un mélange d'oxydes de manganèse et d'oxydes de plomb, le catalyseur étant activé en le chauffant dans un hydrocarbure ou dans l'hydrogène à 300 degrés C-400 degrés C. Ce procédé permet d'obtenir du nitrosobenzène contenant très peu de produits secondaires.
