The specific behavior of aromatic amines in the coordination and extraction processes of isolation and separation of platinum and other metals is discussed using the example of 2(4)-aminopyridines (2(4)-AP). As intrasphere ligands, 2(4)-AP have a high electron-donor capacity due to the pumping of an easily polarizable π-electron density. The chemistry of the extraction of platinum metals, iridium in particular, is considered: depending on the conditions, ion associates, coordination-solvated compounds or compounds containing an amine in the inner and outer coordination sphere of the metal are extracted. In the extraction of simple singly charged anions, there is a violation of the exchange-extraction series established for a large set of aliphatic amines. Soft anions (according to Pearson), for example, SCN- and I-, are best extracted, while for aliphatic amines such an anion is hard СlO4−. In the coordination compounds of platinum metals, 2(4)-AP acts as an electron donor, is coordinated by heterocyclic nitrogen with a redistribution of electron density not only to the accepting metal-complexing agent, but also further along the N-Me-X chain (X is an acido ligand in the composition of the complex), which leads to even greater covalence of the molecule as a whole.

“…Amberlite LA-1 or LA-2 [11], N-methyl-N,N,Ntrioctylammonium chloride [12] mixture of N-n-octylaniline and trioctylamine [13] are successfully employed for the extraction of thorium(IV). Extraction of thorium(IV) was done from 2-octylaminopridine [14] in kerosene along with various organophosphorus compounds like TBP (30%) [15], Cyanex302 [16], triphenylphosphine oxide, di-isodecyl phosphoric acid [17][18][19][20] as well as Di 1(methyl-heptyl) methyl phosphonate [21], The extraction of Th(IV) was investigated by using di(1-methyl-heptyl) methyl phosphonate (DMHMP) in kerosene as an extractant [22].…”

Herein we have developed solvent extraction method for thorium(IV) with 0.15 M N-n decylaniline in xylene from 0.5 M H 2 SO 4. Physicochemical parameters like acid concentration, amine concentration, equilibrium time, phase ratio, diluent, loading capacity to name a few were optimized for the quantitative extraction of thorium(IV). The back-extraction of thorium(IV) from organic phase was done with 0.1 M nitric acid and determined complexometrically. To extend the utility of this method, binary and ternary mixture separation, extraction of thorium(IV) from monazite sand and gas mantle are also investigated.
