Abstract:
1. A process for making an isobutanol-containing product, comprising: contacting a reactant comprising ethanol and methanol with a catalyst at a reaction temperature and pressure sufficient to produce said reaction product, wherein said catalyst is derived from a hydrotalcite of the formula: wherein M M x is 0.66 to 0.1; M′ is (i) one or more divalent members selected from the group consisting of Zn, Ni, Pd, Pt, Fe, Co, and Cu; or (ii) one or more trivalent members selected from the group consisting of Fe, Cr, and Ru; or (iii) a mixture of one or more of said divalent members with one or more of said trivalent members; A′ is an anion of ethylenediaminetetraacetic acid; n′ is absolute value of a sum of an oxidation state of M′ and (−4); provided that if M′ is said mixture, then n′ is calculated according to the following equation: X X A a=0.001 to 1; and y=0 to 4; wherein the hydrotalcite catalyst is partially decomposed.
