Patent ID: 7705192

Claim:
A process for making an isobutanol-containing product, said process comprising: contacting a reactant comprising ethanol and methanol with a catalyst at a reaction temperature and pressure sufficient to produce said 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 )●yH 2 O wherein M 2+ is divalent Mg, or a combination of divalent Mg and at least one divalent member selected from the group consisting of Zn, Ni, Pd, Pt, Co, 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; and y is 0 to 4; wherein the hydrotalcite catalyst is partially decomposed.
