Abstract
L'invention se rapporte à l'industrie chimique. On prépare des composés carbonylés par réaction catalysée de cétones et d'acides carboxyliques en phase vapeur. Un exemple d'une telle réaction est celle de l'acétone avec l'acide pivalique en passant sur un catalyseur dioxyde de cérium-alumine à une température voisine de 470 degrés C pour produire la pinacolone. Application à la préparation de produits intermédiaires pour l'industrie pharmaceutique et pesticide.
