Fundamental studies have been reported using the cationic liquid ion exchanger di(2-ethylhexyl) phosphoric acid in the extraction of uranium from wet-process phosphoric acid (H34), yttrium from nitric acid solution (Hll), nickel and zinc from a waste phsophate solution (P9), samarium, neodymium, and cerium from their chloride solutions (12), aluminum, cobalt, chromium, copper, iron, nickel, molybdenum, selenium, thorium, titanium, yttrium, and zinc (Lll), and in the formation of iron and rare earth di(2-ethylhexyl) phosphoric acid polymers (H12). Other cationic liquid ion exchangers that have been used include naphthenic acid, an inexpensive carboxylic acid to separate copper from nickel (F4), di-alkyl phosphate to recover vanadium from carnotite type uranium ores (M42), and tributyl phosphate to separate rare earths (B24).

Cobalt complexes have frequently been used as catalysts for the oxidation of alcohols. Secondary alcohols were oxidized to ketones in the liquid phase in the presence of mixtures of Co(II) and Co(III) acetates at 60 C in nearly 80% yield [312]. Primary alcohols, on the other hand, gave high yields of the corresponding carboxylic acids in the presence of Co(OAc)3 [313]. Reaction proceeded stepwise through the aldehyde to the acid [314]. Chromium acetate could also be used to catalyze the oxidation of primary alcohols to carboxylic acids at temperatures below 100 °C but manganese and ferrous naphthenates were inactive under these conditions [314].
