초록

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, Na₂ CO₃ 및 K₂HPO₄ 알칼리 수용액에 의한 재추출 실험도 하였다. 실험결과 구연산의 추출에서 2급아민인 di-isotridecylamine(DITDA)이 추출도와 선택성에서 가장 좋았고 용매로서는 n-butylacetate가, modifier로서는 TBP가 우수하였다. 이외에도 수용액의 pH와 추출계의 온도가 낮을수록 추출도가 높았다. 재추출도는 stripping상의 염기도와 온도가 낮을수록 높아졌고 알카리 농도가 커질수록 높아졌다.

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, Na₂CO₃, and K₂HPO₄. Based on the experiment Di-isotridecylamine(secondary amine ) gave higher degree of extraction and more selective than other extractants tested for the extraction of citric acid. N-butylacetate and TBP showed heigher performance for a diluent and modifier, repetitively. The degree of extraction was getting better with decreasing the pH in the aquous phase and the temperature of extraction system. The degree of re-extraction was getting higher with decreasing basicity in the stripping phase and the system temperature, and with increasing the concentration of alkali solution.
