초록

1기압 25 ℃에서 acetonitrile-water-binary solvent를 포함한 4성분 액-액추출계의 상평형에 대하여 연구하였다. Butyl acetate(BAc)-1-butanol를 혼합용매로 사용하였으며, 수용액으로부터 acetonitrile를 추출함에 있어서 혼합용매 사용의 효과를 고찰하기 위하여 각 4성분계에 대한 용해도 곡선, Tie-line, 분배도와 선택도를 측정하였다. 또한 실험에 의한 Tie-line 데이터를 UNIFAC 모델식으로부터 예측된 값들과 비교하였으며, 4성분계 액-액평형에 대한 UNIFAC 모델이 본 실험에 설정된 4성분계에 대하여 3.48 mol%의 평균 RMSD 범위 내에서 Tie-line의 예측이 가능함을 알 수 있었다.

We studied on the phase equilibria of quaternary liquid-liquid extraction system containing acetonitrile-water-binary solvent at 25 ℃, 1 atm. Butyl acetate-1-butanol was used as binary solvents. Binodal curve, tie-line, distribution and selectivity for each quaternary system have been determined in order to investigate the effect of binary solvent in extracting acetonitrile from aqueous solution. These experimental tie-line data were also compared with the values predicted by UNIFAC mode. It was shown that UNIFAC model is capable of predicting the tie-line in these quaternary systems within an average RMSD of 3.48 mol%
