xanthate's Usage Examples:

thiocarbonylthio compounds, such as dithioesters, thiocarbamates, and xanthates, to mediate the polymerization via a reversible chain-transfer process.

consist mainly of thio-carbonyl species such as thiurams, dithiocarbamates, xanthates and organic thioureas; aromatic guanidines are also used.

Flotation: Pyrrhotite is known for flotation via the dixanthogen route, whereas pentlandite forms the metal xanthate.

Alkylation of such thioxanthate anions gives thioxanthate esters, as illustrated.

the fibers with lye, and adds carbon disulfide to form sodium cellulose xanthate.

Nutter, perfected the use of chemical xanthates, replacing the use of oil and easing the workings in the froth cells.

in London SEX (computing), an assembly language mnemonic Sodium ethyl xanthate, or SEX, a chemical compound used in the mining industry Sex-, the Latin.

Industrial applicationsCellulose reacts with carbon disulfide (CS2) in presence of sodium hydroxide (NaOH) to produces sodium cellulose xanthate, which upon neutralization with sulfuric acid (H2SO4) gives viscose rayon or cellophane paper (Sellotape or Scotch Tape).

NaOH → Na2COS2 + H2O Important derivatives of dithiocarbonates are the xanthates (O-esters of dithiocarbonates), with the formula ROCS− 2.

The xanthate is then converted back to a cellulose fiber in a subsequent.

Xanthate anions also undergo alkylation to give xanthate esters, which are generally stable:ROCS2K + R′X → ROC(S)SR′ + KXThe C-O bond in these compounds are susceptible to cleavage by the Barton–McCombie deoxygenation, which provides a means for deoxygenation of alcohols.

Certain xanthate salts and bisxanthates (e.

performed pioneering studies in organosulfur chemistry, discovering the xanthates in 1823.
