| Abstract: | The oxidation of toluene to benzaldehyde catalyzed by the Keggin-type heteropolyacid compound Co3H2PV2Mo10O40 using tert-butyl hydrogen peroxide(TBHP) as the oxidant and acetonitrile as the solvent was investigated.Infrared spectroscopy(IR) and X-ray diffraction(XRD) were used to characterize the catalysts.Experiments showed that reaction temperature 90 ℃ and reaction time 6 h,the conversion of toluene was 28.5% and the selectivity of benzaldehyde was 55.5%. |
