Patent ID: 7745672

Claim:
A process for making a isobutanol-containing reaction 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: [[(M 2+ 1−x M 3+ x (OH) 2 )(A n− x/n )]. y H 2 O][M′A′] z wherein, M 2+ is divalent Mg, or a combination of Mg and at least one divalent member selected from the group consisting of Zn, Ni, Pd, Pt, Go, Fe, and Cu; M 3+ is trivalent Al, or a combination of trivalent Al and at least one trivalent member selected from the group consisting of Fe and Cr; x is 0.66 to 0.1; A n− is CO 3 2− with n=2, or OH − with n=1; M′A′ is a carbonate of at least one divalent metal M′ selected from the group consisting of Zn, Ni, Pd, Pt, Go, Fe, and Cu; and A′ is carbonate; z is any number between 0.001 and 0.5 inclusive; and y is 0 to 4, wherein the hydrotalcite catalyst is partially decomposed.
