Extraction Equilibria

The extraction of L(+) tartaric acid from aqueous solutions by amberlite LA-2 is a secondary amine mixture in different diluent solvents. Extraction equilibria of L(+) tartaric acid by amberlite LA-2 in 1-octanol, cyclohexane, isooctane, hexane, methyl isobutyl ketone (MIBK) solvents at temperature 298.15 K have been measured. The batch extraction experiments distribution coefficients (D), loading factors (Z) and extraction efficiency (E) were calculated. The maximum removal of L(+) tartaric acid is 91 % with MIBK and 0.92 mol.L-1initial concentration of Amberlite LA-2.

Extraction Equilibria

Extraction equilibria in the system aqueous solution of D-tartaric acid/solution of trialkylamine in binary diluent at 25 °C have been investigated. The amine used was a mixture of trialkylamines with C7-C9 alkyls, the diluent was a mixture hydrocarbon (n-heptane, kerosene) and a modifier (octan-1-ol, isodecanol, methyl isobutyl ketone). The effect of solvent composition on equilibrium was investigated and the experimental results were correlated using a mathematical model that takes into account chemical reactions involved in acid/amine complex formation, and the nonspecific effects of the nonideality of the system.

Ionic Associates

A new method has been developed for the indirect determination of nitroso- and nitrophenols by atomic absorption spectrometry (AAS) after extraction of ionic associates involving bipyridylocopper(II) (CuDP) or phenanthrolinocopper(II) (CuPH) complexes. Nitrobenzene and methyl isobutyl ketone appeared to be suitable for the extraction. It was possible to determine several tenths to hundredths of a milligram of nitrophenol in a litre. Extractable associates with CuDP and CuPH are formed by phenols possessing two substituents or by higher molecular weight phenols such as naphthol or hydroxyquinoline. Monosubstituted phenols fail to form associates of this kind.
