Sodium salt of ethyl xanthate (sodium ethylxanthate or sodium O-ethyl dithiocarbonate) Structure of a xanthate ester Cellulose xanthate (orange) A xanthate is a salt or ester of a xanthic acid. The formula of the salt of xanthic acid is [R−O−CS 2] − M + (where R is organyl group and M is usually Na or K). [1] Xanthate also refers to the ...
Sodium ethyl xanthate (SEX) [3] is an organosulfur compound with the chemical formula CH 3 CH 2 OCS 2 Na. It is a pale yellow powder, which is usually obtained as the dihydrate. Sodium ethyl xanthate is used in the mining industry as a flotation agent. [4] A closely related potassium ethyl xanthate (KEX) is obtained as the anhydrous salt.
Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor. [9]Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and chloroform, demonstrating its ability to dissolve a wide range of substances including ethyl cellulose, polyvinyl butyral, oils, alkaloids, and natural ...

Triton X-100 is soluble at 25 °C in water, toluene, xylene, trichloroethylene, ethylene glycol, ethyl ether, ethyl alcohol, isopropyl alcohol, and ethylene dichloride. Triton X-100 is insoluble in kerosene, mineral spirits, and naphtha, unless a coupling agent like oleic acid is used.
An example is sodium ethyl xanthate as a collector in the flotation of galena (lead sulfide) to separate it from sphalerite (zinc sulfide). The polar part of xanthate anion attaches to the ore particles and the non-polar hydrocarbon part forms a hydrophobic layer. The particles are brought to the water surface by air bubbles.
