xanthate

With iodomethane, it is transformed into a xanthate.

Technical grade xanthate salts are usually of 90-95% purity.

The resulted silver xanthate is detected with 10% aqueous solution of iron nitrate.

Sodium ethyl xanthate is predominantly used in the mining industry as a flotation agent.

Sodium ethyl xanthate easily adsorbs on the surface of solid sulfides.

Sodium ethyl xanthate is a pale yellow powder.

The intermediate is a xanthate.

Unlike the related sodium ethyl xanthate, the potassium salt exists as an anhydrous salt.

For example, sodium ethoxide gives sodium ethyl xanthate.

Sodium ethyl xanthate decomposes in water increases with decreasing pH and with increasing temperature.

Perchloric acid method involves dissolution of xanthate in water-free acetic acid.

The xanthate is dissolved in additional sodium hydroxide and allowed to depolymerize to a desired extent, indicated by the solution's viscosity.

In the first step, a potassium xanthate is formed out of the alkoxide and carbon disulfide (CS).

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

This radical reacts with the xanthate 2 to S-methyl-S-methyl dithiocarbonate 7 and the radical intermediate 5.

In the argentometric method, sodium ethyl xanthate is reacted with silver nitrate in a dilute solution.

The higher the ratio of cellulose to combined sulfur, the lower the solubility of the cellulose xanthate.

Sodium ethyl xanthate has moderate oral and dermal toxicity in animals and is irritating to eyes and skin.

In the mercurimetric method, xanthate is dissolved in 40% aqueous solution of dimethylamine, followed by heating and titration with O-hydroxymercuribenzoate.

Viscose is a solution of cellulose xanthate made by treating a cellulose compound with sodium hydroxide and carbon disulfide.

Potassium ethyl xanthate (KEX)

The alkali cellulose is then treated with carbon disulfide to form a solution of sodium cellulose xanthate, which is called viscose.

Potassium amyl xanthate (PAX)

Sodium isobutyl xanthate (SIBX)
