摘要：

The vapor-phase oxidation of 4-picoline to pyridine-4-carboxaldehyde on (VO)2P2O7 has been studied. VOHPO4. 0.5 H2O was used as catalyst precursor. The resulting aldehyde was trapped as oxime with hydroxylamine hydrochloride solution in a subsequent reaction. In the optimum temperature range (683-703 K), a high 4-picoline conversion with good selectivity for the aldehyde was observed.
