Method for Producing a Sorbent for Selective Recovery of Scandium Ions

A method of production of sorbents involving acylation of a macroporous styrene-divinylbenzene copolymer in the presence of the Friedel-Crafts catalyst-aluminum chloride. The acylation reaction is carried out using acetyl chloride in a dichloroethane solvent at boiling the solution. This is followed...

Beschreibung
Zusammenfassung:	A method of production of sorbents involving acylation of a macroporous styrene-divinylbenzene copolymer in the presence of the Friedel-Crafts catalyst-aluminum chloride. The acylation reaction is carried out using acetyl chloride in a dichloroethane solvent at boiling the solution. This is followed by phosphorylation of the obtained acylated copolymer with phosphorus trichloride at room temperature; the product is hydrolyzed with water, washed and dried. The technical result consists in production of a complexing adsorbent highly selective for scandium and simplification of the production process.
