摘要
本文研究了有机胺萃取发酵清液中柠檬酸的动力学,确定了萃取机理,考察了添加剂200~#溶剂油。醋酸丁酯和油酸以及温度对萃取的影响。
The extraction of citric acid from fermentation aqueous solution by alkyt amine with single, drop method has been studied. The orders of this reaction have been found to be 1 and 1.5 for concentration of citric acid in aquecus phase and alkyl amine in organic phase respectively. The rate constant was calculated to be 0.002310 at 303K. The influences of oleic acid, butyl acetate and 200#paraffin concentration on the extraction rate arc also discussed.
