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 and through reaction in the presence of a source of hydrogen and of a mixed oxide catalyst, for example, a Zn x Zr y O z mixed oxide catalyst. A variety of commercially valuable products may be made in turn from the various C 3 , C 4 and C 5 constituents of the product mixture. |
