About Potassium Ethylxanthate

Potassium Ethylxanthate (also known as Potassium ethyl xanthate and Potassium ethyl xanthogenate) is one of numerous organosulfur compounds manufactured by American Elements under the trade name AE Organometallics™. Potassium ethylxanthate is primarily used as a surfactant, chemical synthesis reagent, and a flotation agent/metal ion extractor in the mining industry. American Elements supplies organometallic compounds in most volumes including bulk quantities and also can produce materials to customer specifications. Most materials can be produced in high and ultra high purity forms (99%, 99.9%, 99.99%, 99.999%, and higher) and to many standard grades when applicable including Mil Spec (military grade), ACS, Reagent and Technical Grades, Pharmaceutical Grades, Optical, Semiconductor, and Electronics Grades.

Elemental PotassiumSee more Potassium products. Potassium (atomic symbol: K, atomic number: 19) is a Block S, Group 1, Period 4 element with an atomic weight of 39.0983. The number of electrons in each of Potassium's shells is [2, 8, 8, 1] and its electron configuration is [Ar] 4s1. The potassium atom has a radius of 227.2 pm and a Van der Waals radius of 275 pm. Potassium was discovered and first isolated by Sir Humphrey Davy in 1807. Potassium is the seventh most abundant element on earth. It is one of the most reactive and electropositive of all metals and rapidly oxidizes. As with other alkali metals, potassium decomposes in water with the evolution of hydrogen because of its reacts violently with water, it only occurs in nature in ionic salts.Potassium Bohr Model In its elemental form, potassium has a silvery gray metallic appearance, but its compounds (such as potassium hydroxide) are more frequently used in industrial and chemical applications. The origin of the element's name comes from the English word 'potash,' meaning pot ashes, and the Arabic word qali, which means alkali. The symbol K originates from the Latin word kalium.


See more Sulfur products. Sulfur (or Sulphur) (atomic symbol: S, atomic number: 16) is a Block P, Group 16, Period 3 element with an atomic radius of 32.066. Sulfur Bohr ModelThe number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s2 3p4. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.
