Abstract

L'invention concerne un procédé perfectionné de production de méthylmercaptan par réaction d'oxyde de carbone, d'hydrogène et d'hydrogène sulfuré en présence d'un catalyseur à haute température et à haute pression. Le perfectionnement consiste à utiliser un catalyseur solide à une seule phase, fixé sur un support, par mélange d'un oxyde, d'un sulfure, d'un hydroxyde ou d'un sel d'un métal choisi entre le fer, le nickel, le chrome, le cobalt et le molybdène avec une amine organique ou une base minérale de métal alcalin qui est un oxyde, un hydroxyde, un sulfure ou un sel, puis à sulfurer le mélange. Le méthylmercaptan est utilisé comme composé intermédiaire pour la fabrication de divers produits chimiques destinés à l'agriculture et comme matière première dans la production de la méthionine.
