Brief overview

Sodium isopropyl xanthate (SIPX) is a pale to grey yellow salt. Xanthate salts are produced by the reaction of an alcohol with sodium hydroxide and carbon disulfide. The reaction involves the attack of the alkoxide salt.

ROH + CS2 + NaOH ROCS2Na + H2O

Virtually any alcohol can be used in this reaction. Technical grade xanthate salts are usually of 90–95% purity. Impurities include alkali-metal sulfide, sulfate, trithiocarbonates, thiosulfate, sulfite, or carbonate as well as residual raw material such as alcohol and alkali hydroxide. These salts are available commercially as powder, granules, flakes, sticks, and solutions are available.

 

 

Manufacturing Process

Xanthate salts are produced by the reaction of an alcohol with sodium or potassium hydroxide and carbon disulfide:

ROH + CS2 + KOH ROCS2K + H2O

The reaction involves the attack of the alkoxide salt. For example, sodium ethoxide gives sodium ethyl xanthate. Virtually any alcohol can be used in this reaction. Technical grade xanthate salts are usually of 90–95% purity. Impurities include alkali-metal sulfide, sulfate, trithiocarbonates, thiosulfate, sulfite, or carbonate as well as residual raw material such as alcohol and alkali hydroxide. These salts are available commercially as powder, granules, flakes, sticks, and solutions are available. Some commercially important xanthate salts include:

sodium ethyl xanthate (SEX), CH3CH2OCS2Na,

potassium ethyl xanthate, CH3CH2OCS2K,

sodium isopropyl xanthate (SIPX)

sodium isobutyl xanthate (SIBX)

potassium amyl xanthate (PAX)

The OCS2 core of xanthate salts and esters is characteristically planar. The central carbon is sp-hybridized.

Mining

Collectors are used in mineral processing industry for recovery of metals. They are organic compounds which make the minerals water repellant by absorption of molecules or ions. Sodium isobutyl xanthate is largely used in the mining industry as flotation agent for recovery of metals, such as copper, nickel, silver or gold, as well as solid metal sulfides or oxides from ore slurries. The polar part of xanthate molecule attaches to the ore particles with the non-polar hydrocarbon part sticking out and forming a hydrophobic layer. Then the particles are brought to the water surface by air bubbles.


Other Application
It is also sometimes used to accelerate vulcanization in rubber industry.
