| 摘要: 本文提供了制备固体过氧钼酸的新方法,它以Na2MoO4为原料,按Mo:H2O2=2.00:1.05(摩尔比)和游离酸度为0.40mole/dm3的量加入H2O2和HNO3,然后在50℃条件下加热20小时,析出Mo:(O2):H2O=2:1:2的固体过氧钼酸,得率96%。用热分析和超高真空程序升温质谱研究了它的性质,并推断其可能结构。 |

| Abstract: A new method is purposed for the preparation of peroxomolybdic acid in this paper. The reaction proceeded for 20 hours at 50℃ using H2O2 as complex agent, Na2MoO4 as starting material (Mo:H2O2 = 2.00:1.05) and the free acidity of solution was 0.40 mole HNO3 / dm3.The yield was 96%.Its chemical component shows the ratio Mo:(O2):H2O = 2:1:2. The physical properties of the acid were studied by thermal analysis and mass spectroscopy detection, and the structure of this compound has also been inferred. |
