Abstract
The kinetics for extraction recovery of acetate ions from simulated waste streams in chloromycetin production by Aliquat 336 (a quaternary amine) and tri-n-butylphosphate (TBP) in xylene were examined using a microporous membrane-based stirred cell. The waste stream typically contained 15.4% acetic acid, 8.8% sodium acetate, and 4.7% (w/w) NaCl. The stirred cell could give intrinsic rates for formation of the complex occurring at or near the organic-aqueous interface. It was shown that the extraction rate with TBP was higher than that with Aliquat 336. The effect of temperature (288-318 K) on the reaction rate with TBP was also examined and the activation energy (54.5 kJ mol-1) was obtained.
