Synergistic Solvent Extraction Is Driven by Entropy

Is soft physics entropy driven?

The soft physics, pT < 2 GeV/c, observables at both RHIC and the SPS have now been mapped out in quite specific detail. From these results there is mounting evidence that this regime is primarily driven by the multiplicity per unit rapidity, dNch/dη. This suggests that the entropy of the system alone is the underlying driving force for many of the global observables measured in heavy-ion collis...

Synthesis of Phthalocyanine derivatives by synergistic effect of catalysts over nanodimensional zeolites under solvent-free conditions

Copper (II) phthalocyanine and 2,9,16,23 tetrakis nitro copper (II) phthalocyaninehas been synthesized respectively from phthalonitrile and 4-nitro phthalonitrile under solvent-free condition using two different catalystsovernanodimensionalzeolites. 4-Nitro phthalonitrile synthesized from phthalimide in three steps. The newly prepared compounds have been characterized by IR, UV-Vis, 1</sup...

4 Solvent Extraction Equilibria

The ability of a solute (inorganic or organic) to distribute itself between an aqueous solution and an immiscible organic solvent has long been applied to separation and purification of solutes either by extraction into the organic phase, leaving undesirable substances in the aqueous phase; or by extraction of the undesirable substances into the organic phase, leaving the desirable solute in th...

Separation of nickel and cobalt from calcium, magnesium and manganese by solvent extraction with synergistic mixtures of carboxylic acids

The potential use of synergistic mixtures of reagents for the solvent extraction of nickel (and cobalt) from lateritic leach liquors was pointed out in the early 1980s by Grinstead, who used dinonylnaphthalene sulphonic acid in conjunction with some 2-pyridyl compounds for the recovery of these metals from slightly acidic solutions1,2. Shortly thereafter, studies at Mintek revealed marked syner...
