Ammonium Dimolybdate, with the CAS number 27546-07-2, is a chemical compound that has gained significant attention in various industries. It is typically presented as a white or light yellow crystalline powder. The molecular formula of ammonium dimolybdate is (NH₄)₂Mo₂O₇, and its molecular weight is approximately 339.98 g/mol. This product is often produced through a series of chemical reactions and purification processes in a factory - scale setting, ensuring high - quality and stable supply at a low price.
It has good solubility in water and is relatively stable under normal storage conditions. The purity of the factory - supplied ammonium dimolybdate can usually reach over 99%, which meets the requirements of most industrial applications.
Ammonium dimolybdate has a wide range of applications in different fields:
When using ammonium dimolybdate, the following steps and precautions should be followed:
Almacenamiento: Store ammonium dimolybdate in a cool, dry, and well - ventilated place. Keep it away from sources of ignition and oxidizing agents. It should be stored in a sealed container to prevent moisture absorption and contamination.
Manejo de: Wear appropriate personal protective equipment, such as gloves and goggles, when handling ammonium dimolybdate. Avoid inhalation of dust and contact with skin and eyes. If contact occurs, immediately rinse with plenty of water and seek medical advice if necessary.
Usage in Alloys: When using it in alloy production, accurately weigh the required amount of ammonium dimolybdate according to the alloy formula. Add it to the molten metal and stir evenly to ensure uniform distribution in the alloy.
Usage in Catalyst Preparation: Dissolve ammonium dimolybdate in an appropriate solvent according to the catalyst preparation process. Then mix it with other components and carry out subsequent steps such as precipitation, calcination, and activation.
Case 1: Alloy Production in an Automobile Parts Manufacturer
An automobile parts manufacturer needed to improve the quality of its engine components. They used ammonium dimolybdate as an additive in the production of a specific alloy for engine pistons. By adding an appropriate amount of ammonium dimolybdate, the strength and wear resistance of the alloy were significantly improved. The pistons made from this alloy showed better performance in high - temperature and high - pressure environments, reducing the failure rate and extending the service life of the engine components. The factory - supplied ammonium dimolybdate at a low price also helped the manufacturer control costs.
Case 2: Petrochemical Catalyst Application
A petrochemical company was facing challenges in meeting the strict sulfur content requirements for its gasoline products. They used ammonium dimolybdate to prepare a hydrodesulfurization catalyst. The catalyst showed high activity and selectivity in removing sulfur compounds from gasoline. After using the new catalyst, the sulfur content in the gasoline was reduced to a very low level, meeting the market and
