Short description

Chemical name: Potassium Ethyl Xanthate (PEX) Shipping name: Carbonodithioic Acid, O-ethyl ester, Potassium salt Chemical formula: CH3CH2OC Molecular weight: 160.3 CAS NO: 140-89-6 EINECS Number: 205-439-3 Physical: Yellow or light gray powder or powder flowing freely and soluble in water. Potassium ethyl xanthate (KEX) is an organosulfur compound with the chemical formula CH3CH2OCS2K. It is a pale yellow powder that is used in the mining industry for the separation of ores. Unlike the related sodium ethyl xanthate, the potassium salt exists as an anhydrous salt. Applications: Potassium ethyl xanthate is used in the mining industry as flotation agent for extraction of the ores of copper, nickel, and silver. The method exploits the affinity of these "soft" metals for the organosulfur ligand. Potassium xanthate is a useful reagent for preparing xanthate esters from alkyl and aryl halides. The resulting xanthate estes are useful intermediates in organic synthesis.
