Abstract

L'invention se rapporte à l'industrie chimique. Le procédé de préparation d'une cétone de formule R CH2 CH2 COCH3 , ou R est un groupe activant est caractérisé par le fait qu'il consiste à mélanger de l'acétone et un composé de formule RCH2 X où R est un groupe activant choisi dans le groupe comprenant l'hydrogène et les radicaux alkyle et aryle et X est un radical fortement mobile, à faire passer le mélange à travers une couche catalytique constituée essentiellement par un composé de dioxyde de cérium sur un support d'alumine, et à récupérer le produit. Application à la préparation de produits intermédiaires pour l'industrie pharmaceutique et pesticide.The invention relates to the chemical industry. The process for preparing a ketone of formula R CH2 CH2 COCH3, where R is an activating group is characterized by the fact that it consists of mixing acetone and a compound of formula RCH2 X where R is an activating group chosen in the group comprising hydrogen and the alkyl and aryl radicals and X is a highly mobile radical, in passing the mixture through a catalytic layer consisting essentially of a compound of cerium dioxide on an alumina support, and in recovering the product. Application to the preparation of intermediate products for the pharmaceutical and pesticide industry.
