Highly Efficient Solvent Extraction of Water-Soluble Macrocyclic Metal Ligands, Hydroxycalix[n]arene-p-sulfonates (n = 4, 6, 8) with Trioctylmethylammonium Chloride

Water-soluble hydroxycalix[n]arene-p-sulfonates, 1nn− (n = 4, 6, and 8), were quantitatively extracted from an aqueous solution into chloroform with trioctylmethylammonium ion (TMA+) over a wide pH range. The extraction reaction of 1nn− with TMA+Cl− and the extraction constants were determined from...
