[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of ammonium heptamolybdate, is ammonium heptamolybdate dangerous goods?

Properties of Ammonium Heptamolybdate

Ammonium heptamolybdate (Ammonium Heptamolybdate) is an inorganic compound with the chemical formula (NH4)6Mo7O24 · 4H2O. This compound usually appears as a white or yellowish crystalline powder, which is easily soluble in water, but has a low solubility in alcoholic solvents. Its aqueous solution is strongly acidic and has good stability, but it will decompose under high temperature or strong acid conditions. Ammonium heptamolybdate is stable in the air and is not easy to absorb moisture, but it will absorb moisture when exposed to a humid environment for a long time.

Ammonium heptamolybdate uses

Ammonium heptamolybdate is widely used in chemical industry. It is an important molybdenum source material and is widely used in the production of other molybdenum compounds, such as sodium molybdate and ammonium molybdate. Ammonium heptamolybdate plays a key role in catalyst production, especially in petrochemical and organic synthesis reactions, and is used as a desulfurization catalyst and a hydrogenation catalyst. It is also used in metal surface treatment, the electroplating industry, and the preparation of preservatives. Ammonium heptamolybdate is also used as a reagent in analytical chemistry for the detection of elements such as phosphorus and arsenic.

Ammonium heptamolybdate upstream raw material

The main raw materials for the production of ammonium heptamolybdate are molybdenum ore and ammonia. After roasting and dissolution treatment of molybdenum ore, sodium molybdate solution is obtained, and then molybdic acid is obtained by acidification treatment. Molybdic acid reacts with ammonia to generate ammonium heptamolybdate solution, which is crystallized, filtered and dried to obtain the finished product. In the production process, acid-base balance and reaction temperature are key control parameters, which directly affect the purity and yield of the product.

Ammonium heptamolybdate downstream products

Ammonium heptamolybdate, as an important intermediate, has a wide range of downstream products. It is widely used in the production of high-purity molybdenum powder, molybdenum tablets and molybdenum rods and other molybdenum products, used in electronics, aerospace and national defense and other high-tech fields. Ammonium seven molybdate is also an important raw material for the preparation of sodium molybdate, potassium molybdate and other molybdenum salts. These molybdenum salts are widely used in glass, ceramics, pigments and fertilizers. Ammonium heptamolybdate can also be used for the synthesis of efficient catalysts, used in petroleum refining and organic synthesis industry.

Ammonium heptamolybdate storage method

Ammonium heptamolybdate needs to be stored in a dry, cool environment, away from direct sunlight and high temperatures. The storage area should be well ventilated, away from ignition and heat sources. Contact with strong acids, strong bases and oxidants should be avoided to prevent chemical reactions. The packaging material is usually a plastic bag or a woven bag lined with a plastic film to prevent moisture. Use protective gloves and masks to avoid dust inhalation or skin contact.

Ammonium heptamolybdate market status and prospects

At present, the market demand for ammonium heptamolybdate is growing steadily, mainly due to its wide application in the fields of catalysts, electronic materials and chemical intermediates. With the advancement of global industrialization, the demand for molybdenum products and molybdenum compounds continues to rise, driving the market expansion of ammonium heptamolybdate. In the future, with the improvement of environmental protection requirements and the continuous emergence of new technologies, the application prospects of ammonium heptamolybdate in green catalysts and high-performance materials are broad, and it is expected to usher in greater market opportunities.

Environmental Protection and Safety

In the production and use of ammonium heptamolybdate, strict compliance with environmental and safety regulations is required. Waste water and waste gas treatment facilities should be improved to prevent the discharge of pollutants from causing harm to the environment. Operators should be professionally trained and familiar with chemical safety knowledge to ensure personal safety during operation. Wastes shall be classified and treated in accordance with regulations to avoid secondary pollution to the environment.

Conclusion

As an important molybdenum compound, ammonium heptamolybdate has been widely used in chemical industry, electronics, catalysis and other fields. Its production process needs to be strictly controlled to ensure product quality and environmental protection. With the progress of technology and the change of market demand, the application prospect of ammonium heptamolybdate will be broader. In the process of development, enterprises should pay attention to scientific and technological innovation and environmental protection management in order to achieve sustainable development.
