Potassium manganate when [] < 1M, follows bimolecular kinetics. See for a list. Potassium manganate Potassium manganate is the inorganic compound with the formula KMnO. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO), a common chemical. Occasionally, potassium manganate and potassium "per"manganate are confused, but they are different compounds with distinctly different properties. KMnO is a salt, consisting of K cations and MnO anions. X-ray crystallography shows that the anion is tetrahedral, with Mn-O distances of 1.66 Å, ca. 0.03 Å longer than the Mn-O distances in KMnO. It is isostructural with potassium sulfate. The industrial
Potassium ethyl xanthate as the anhydrous salt and is nonhygroscopic. 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. The LD50 is 683 mg/kg (oral, rats) for potassium ethyl xanthate. Potassium ethyl xanthate Potassium ethyl xanthate (KEX) is an organosulfur compound with the chemical formula CHCHOCSK. It is a pale yellow powder
