TL;DR: In this paper, the synergic extraction of vanadium with 8-quinolinol in the presence of alcohol can be accounted for in terms of the following reaction, i.e. esterification: VO(Ox) 2 (OH) 0 + ROH 0 = VO( Ox) 2(OR) 0+ H 2 O 0

TL;DR: The ability of tetra(p-t-butyl)tetrathiacalix[4]arenetetrol (TCA, H4L) to bind metal ions was investigated via a solvent extraction study as discussed by the authors.
Abstract: The ability of tetra(p-t-butyl)tetrathiacalix[4]arenetetrol (TCA, H4L), a cyclic tetramer of p-(t-butyl)phenol bridged with four epithio groups, to bind metal ions was investigated via a solvent extraction study. Although tetra(p-t-butyl)calix[4]arenetetrol (CA) has very poor affinity for transition metal ions (M2+), TCA is an excellent extractant of these metal ions. The chemical formulae of the extracted TCA metal complexes were found by slope analysis to be neutral 1 : 1 complexes [MH2L]. The origin of the high affinity of TCA for transition metal ions is discussed, in which it is suggested that ligation of the epithio group is important as evidenced by an NMR study of the [ZnH2L] complex.
