Catalytic synthesis of isobutyraldehyde from methanol and n-propyl alcohol over titanium oxide-supported vanadium oxide catalysts

“…Currently, isobutyraldehyde is obtained from the separation of the byproducts in the OXO process (Paulik, 1972). Recently, we have developed a 0888-5885/93/2632-0030$04.00/ 0 © 1993 American Chemical Society novel method for synthesizing isobutyraldehyde selectively from methanol and ethanol in one step by using titanium oxide-supported vanadium oxide (V/Ti02) as a catalyst (Wang and Lee, 1991). In an extension of these studies, we have found that V/Ti02 is an effective catalyst for the reaction of methanol and n-propyl alcohol (PrOH) to form isobutyraldehyde and for the catalytic alkylation of other alcohols, aldehydes, and ketones by using methanol as the methyl group source.…”
