Abstract
For elucidation of various parameters' effects on the reactive extraction of citric acids, citric-acetic-lactic acid system with various carriers, diluents, and modifiers were investigated. Carries used were secondary amines, tertiary amines, and solvation extract. Dileunts were n-butylacetate, methoisobutylketon(MIBK), kerosine, and xylene. Modifiers were TBP and isodecanol. The effects of temperature and pH in aquous phase were studied, and equilibrium constants for the reactive extraction were obtained. The re-extraction was performed by alkali solutions such as NaOH,
구연산-초산-유산계에서 구연산의 반응추출에 영향을 미치는 여러 인자를 규명하기 위하여 추출제로 2급과 3급아민 및 용매화추출제를, 용매로 n-butylacetate, MIBK, kerosine 및 xylene 등을, modifier로서 tributyl-phosphate(TBP)와 isodecanol이 이용되었다. 그 외에 수용액상의 pH와, 온도의 영향을 연구하였고 평형상수도 얻었다. NaOH,
