CAS 140-90-9: Sodium xanthate
Description:Sodium xanthate, with the CAS number 140-90-9, is an organic compound that belongs to the class of xanthates, which are esters of xanthic acid. It appears as a yellowish to white solid and is highly soluble in water, making it useful in various applications. Sodium xanthate is primarily utilized in the mining industry as a flotation agent for the separation of sulfide minerals, particularly in the extraction of copper, lead, and zinc. It acts by selectively binding to mineral surfaces, enhancing their hydrophobicity and facilitating their separation from gangue materials. The compound is also employed in the production of viscose rayon and as a reagent in organic synthesis. Sodium xanthate is known for its strong reducing properties and can decompose under certain conditions, releasing toxic gases such as carbon disulfide. Safety precautions are necessary when handling this substance, as it can be harmful if ingested or inhaled, and it may cause skin and eye irritation. Proper storage and handling practices are essential to mitigate risks associated with its use.
