Improved supported, mixed-metal oxide oxidation catalysts are prepared by conditioning a devolatilized catalyst precursor with an alcohol prior to calacining the precursor to a finished catalyst. For example, a promoted bismuth phosphomolybdate oxidation catalyst useful for converting propylene to acrolein demonstrates enhanced performance characteristics when the devolatilized catalyst precursor is subjected to boiling ethanol prior to calcining it to a finished catalyst.

An improved method for preparing a supported, mixed-metal oxide oxidation catalyst, the method comprising: (1) forming a catalyst precursor with a volatile content from a support and the mixed-metal components, (2) reducing the volatile content of the precursor of (1), and (3) calcining the precursor of (2) to a finished catalyst, the improvement comprising conditioning the catalyst precursor with a solution of at least one C1-C8 aliphatic alcohol that is substantially free of water and is substantially removed upon calcination subsequent to reducing the volatile content of the precursor and prior to calcining the precursor to a finished catalyst.
