A series of heteropolyacid phase transfer catalysts containing high-valent molybdenum, vanadium and other metals were designed and synthesized to catalyze the oxidation of cyclopentene to glutaraldehyde, and the best imidazolyl molybdate-vanadate catalyst [C4H9N2C3H3(CH3)]5VMo7O26 was screened out. The conditions of solvent type, H2O2 dosage, catalyst dosage, reaction temperature and time were optimized. Under the optimized reaction conditions [V(ethyl acetate)∶V(water)=4∶1, n(Cat.)∶n(H2O2)∶n(CPE)=1∶170∶41.6, 50 ℃, 6 h], 88.7% cyclopentene conversion and 62.1% glutaraldehyde selectivity were obtained, and the catalyst still maintained high catalytic activity after 7 cycles of use.
