磷钨酸锌绿色催化合成苯甲醛

用磷钨酸和氯化锌为起始原料合成了磷钨酸锌,并用来催化30%双氧水氧化苯甲醇制备苯甲醛的反应.讨论了焙烧温度、催化剂用量、氧化剂用量、反应温度、反应时间五种因素对催化活性的影响,从而确定了最佳反应条件,同时还研究了催化剂的重复使用性能和在其他醇氧化反应中的活性.

Benzaldehyde Synthesized with Zinc Phosphotungstate by Green Catalysis

Zinc phosphotungstate（ZnPW） was prepared with phosphotungstic acid（HPW） and zinc chloride as staring materials and used in the catalystic oxidation of benzyl alcohol（BzOH） to benzaldehyde（BzH） with H2O2（30% w/w）.Five factors involving calcination temperature,the amount of catalyst,the dosage of H2O2,reaction temperature and reaction time and their influences on catalystic activity are carefully investigated, and the optimal reaction conditions are obtained.The reuse and promotion of the catalyst in oxidation of other alcohols are studied.
