Summary:A process is described for making a product mixture including isobutene, propylene, 1-butene, 2-butene, 2-methyl-1-butene and 2-methyl-2-butene from a mixture of acetic acid and propionic acid through reaction in the presence of a source of hydrogen and of a mixed oxide catalyst, for example, a ZnxZryOz mixed oxide catalyst. A variety of commercially valuable products may be made in turn from the various C3, C4 and C5 constituents of the product mixture L'invention concerne un procédé pour produire un mélange de produits comprenant isobutène, propylène, 1-butène, 2-butène, 2-méthyl-1-butène et 2-méthyl-2-butène à partir d'un mélange d'acide acétique et d'acide propionique via une réaction en présence d'une source d'hydrogène et d'un catalyseur en oxyde mixte, par exemple, un catalyseur en oxyde mixte contenant ZnxZryOz. Une variété de produits à valeur commerciale peuvent être produis à leur tour à partir de constituants variés C3, C4 et C5 du mélange de produits.
