Catalytic Oxidation of toluene to benzaldehyde over Keggin-type heteropoly Compounds

摘要:

研究了以TBHP(叔丁基过氧化氢)为氧化剂，乙腈为溶剂的条件下，利用Keggin型Co3H2PV2Mo10O40杂多酸盐为催化剂催化氧化甲苯制备苯甲醛。用红外光谱分析(IR)、X射线衍射(XRD)方法对催化剂进行了表征。实验表明：在90℃反应6h，得到甲苯转化率为28.50%，苯甲醛的选择性达到55.50%。

Abstract:

Oxidation of toluene to benzaldehyde catalyzed by Keggin-type heteropoly compound Co3H2PV2Mo10O40 using TBHP(tert-butyl hydrogen peroxide) as oxidant and acetonitrile as solvent was investigated. Using infrared spectroscopy(IR),X-ray diffraction (XRD) were used to characterize the catalysts. Experiments showed that reaction temperature 90℃ and reaction time 6h, the conversion of toluene was 28.50% and the selectivity of benzaldehyde was 55.50%.
