Parameters of Molybdenum dichloride dioxide MoO2Cl2 99.9% powder
Molybdenum dichloride dioxide, also known as MoO2Cl2, is a chemical compound that consists of molybdenum (Mo), oxygen (O), and chlorine (Cl) in a stoichiometric ratio of one molybdenum atom bonded to two oxygen atoms and two chlorine atoms. This compound holds significance due to its unique properties and potential applications in various industries.
Molybdenum dichloride dioxide is an ionic solid with a chemical formula indicating a 1:1:2 molar ratio. It crystallizes in the monoclinic crystal system, adopting a layered structure, which contributes to its characteristic properties. The compound exhibits a pale yellow or greenish-yellow color, depending on the purity level, with a melting point around 360-370°C (680-700°F). At room temperature, it is stable in dry conditions but can hydrolyze in the presence of moisture, releasing chlorine gas.
The compound’s high purity, as stated at 99.9%, ensures a low impurity content, making it suitable for demanding applications where purity is crucial. The purity parameter is often indicated by the percentage of the desired active compound, with 99.9% meaning that only 0.1% of impurities are present. This high purity is achieved through rigorous purification processes, such as sublimation, recrystallization, or chemical refining.
Molybdenum dichloride dioxide is primarily used in catalysts, particularly in the petrochemical industry. It acts as a catalyst in various reactions, including hydrodesulfurization, hydrogenation, and hydrocracking, where it enhances the conversion of hydrocarbons into more valuable products. Its ability to selectively adsorb sulfur species and promote their removal makes it a vital component in refining processes.
Moreover, MoO2Cl2 has applications in the semiconductor industry, where it serves as a precursor in the fabrication of molybdenum-based thin films and electronic devices. The compound can be reduced under specific conditions to form molybdenum metal, which is essential for the growth of high-k dielectrics and other advanced materials.
In addition to its industrial uses, MoO2Cl2 has shown potential in environmental remediation. It can act as a sorbent for heavy metals and other pollutants, demonstrating its capability to remove contaminants from water and air.
However, it is important to note that molybdenum dichloride dioxide is a corrosive substance and should be handled with care, as it can cause skin irritation and respiratory issues upon inhalation. Proper safety measures, such as protective gear and well-ventilated workspaces, are necessary when working with this compound.
In summary, molybdenum dichloride dioxide, with its high purity, is a versatile chemical compound with significant applications in catalysts, electronics, and environmental remediation. Its layered structure and unique properties make it a valuable material in various sectors, while the importance of handling it safely cannot be overstated.
