Abstract:
The invention relates to a catalyst composition comprising a mixed oxide of vanadium, titanium, and phosphorus modified with alkali metal. The titanium component is derived from a water-soluble, redox-active organo-titanium compound. The catalyst composition is highly effective at facilitating the vapor-phase condensation of formaldehyde with acetic acid to generate acrylic acid, particularly using an industrially relevant aqueous liquid feed.
