Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 16961-25-4, is researched, SMILESS is Cl[Au-](Cl)(Cl)Cl.[H]O[H].[H]O[H].[H]O[H].[H+], Molecular AuCl4H7O3Journal, Separation and Purification Technology called The recovery and selective extraction of gold and platinum by novel ionic liquids, Author is Boudesocque, Stephanie; Mohamadou, Aminou; Conreux, Alexandra; Marin, Beatrice; Dupont, Laurent, the main research direction is gold platinum extraction ionic liquid dicyanamide thiocyanato imide.Recommanded Product: Hydrogen tetrachloroaurate(III) trihydrate.
Ionic liquids bearing tetrahexylammonium and tetraoctylammonium cations and halide (Br-), dicyanamide (Dca-), thiocyanato (SCN-) and bis(trifluoromethysulfonyl)imide (Tf2N-) by liquid-liquid extraction were studied on Au(III), Pt(II) and Pt(IV) extraction All the system show excellent extractability of Au(III). It is the same for Pt(II) and Pt(IV) except for Tf2N- based ionic liquids which do not extract Pt(II) and Pt(IV) and constitute selective system for the separation of Au and Pt from aqueous effluents. The influence of acid concentration on extraction yield is evaluated. The anion-exchange mechanism of Au(III), Pt(II) and Pt(IV) was confirmed. Reductive stripping was used for the recovery of Au(III) and Pt(IV). Tf2N- based ionic liquids show an excellent recovery of Au(III) using thiourea as back-extractant.
