Ammonium molybdate is an important inorganic salt, which is widely used in the field of chemical production raw materials. It has unique properties and uses, and has played an important role in promoting the development of the chemical industry. This article will detail the properties and uses of ammonium molybdate.

1. the properties of ammonium molybdate

1. physical properties: ammonium molybdate is a white or slightly yellowish crystalline powder, with a high melting point and boiling point, insoluble in water, but soluble in acid and alkaline solution.

2. chemical properties: ammonium molybdate has strong oxidation, can react with reducing agent to generate molybdenum blue, also can react with alkali metal hydroxide to generate molybdate. In addition, ammonium molybdate has good thermal stability and can be decomposed at high temperature to form molybdenum oxide.

2. the use of ammonium molybdate

1. catalyst: ammonium molybdate can be used as a catalyst for petroleum cracking, alcohol oxidation, esterification and other chemical process, can improve the reaction rate and selectivity.

2. preservatives: ammonium molybdate has good antibacterial properties, can be used as a preservative for wood, paint, plastic and other products, can extend the service life of the product.

3. pigment: ammonium molybdate can be used as a pigment for glass, ceramics, enamel and other industries coloring, with good light resistance and heat resistance.

4. analytical reagent: ammonium molybdate can be used as analytical reagent for the determination of molybdenum content in steel, alloy, ore and other substances, with high sensitivity and accuracy.

5. pharmaceutical intermediates: ammonium molybdate can be used as pharmaceutical intermediates for the preparation of anticancer drugs, antibacterial drugs, etc., with good pharmacological effects and therapeutic effects.

3. ammonium molybdate production method

ammonium molybdate production method mainly has two kinds: one is the molybdic acid and ammonia reaction system, the other is the molybdenum concentrate through roasting, leaching, impurity removal, crystallization and other processes. No matter which method is used, it is necessary to strictly control the production process conditions to ensure product quality.

4. ammonium molybdate market prospects

With the continuous development of science and technology, ammonium molybdate in the chemical production of raw materials in the field of more and more widely, the market demand is also gradually increasing. In the future, with the continuous emergence of new technologies and new materials, the application field of ammonium molybdate will be further expanded, and the market prospect is very broad.

In short, as an important inorganic salt, ammonium molybdate has unique properties and a wide range of uses, which plays an important role in promoting the development of the chemical industry. In the future, with the increasing market demand and the continuous progress of technology, the application prospect of ammonium molybdate will be broader.
