采用水热法制备混合价态的钒磷氧催化剂,并对其进行x射线衍射仪表征。以H2O2为氧化剂,考察该催化剂对1-甲氧基-2-丙醇催化氧化合成1-甲氧基-2-丙酮的催化活性,通过实验,确定了最佳反应条件:反应温度70℃,反应时间7 h,1-甲氧基-2-丙醇1 m L,催化剂0.1 g,H2O2 15.2 m L时,1-甲氧基-2-丙醇转化率为86.9%,1-甲氧基-2-丙酮选择性为33.2%及收率为20.7%。 The vanadium phosphorus oxy-catalyst with mixed valences was prepared by hydrothermal method and characterized by X-ray diffraction. The catalytic activity of the catalyst for the 1-methoxy-2-propanol to 1-methoxy-2-propanal was investigated by using H2O2 as the oxidant. The optimal reaction conditions were determined by the experiment: the reaction temperature was 70 ℃, Reaction time 7 h, 1-methoxy-2-propanol 1 m L, catalyst 0.1 g and H2O2 15.2 m L, the conversion of 1-methoxy-2-propanol was 86.9% -2-propanone selectivity of 33.2% and yield of 20.7%.
