Abstract
1기압 298.15 K에서 water + tetrahydrofuran + butyl acetate + isoamyl alcohol를 포함한 4성분 액-액추출계의 상평형에 대하여 연구하였다. Butyl acetate + isoamyl alcohol을 혼합용매로 사용하였으며, 수용액으로부터 tetrahydrofuran를 추출함에 있어서 혼합용매 사용의 효과를 고찰하기 위하여 각 4성분계에 대한 용해도 곡선, 대응선(Tie-line), 분배도, 선택도를 측정하였다. 또한 실험에 의한 대응선(Tie-line) 데이터를 UNIFAC 모델식으로부터 예측된 값들과 비교한 결과, 액-액평형에 대한 UNIFAC 모델이 본 실험에 설정된 4성분계에 대하여 혼합용매 비율 75/25, 50/50, 25/75에 따라 3.35, 5.21, 5.65%의 편차가 나타남을 알 수 있었다.
Liquid-liquid equilibrium data for the quaternary system water +tetrahydrofuran + butyl acetate + isoamyl alcohol mixture were measured at 298.15 K and atmospheric pressure. Binodal curves, tie-lines, distribution, and selectivity for the quaternary system have been determined in order to investigate the effect of using binary solvents, butyl acetate and isoamyl alcohol, on extracting tetrahydrofuran from aqueous solution. In addition, these experimental tie-line data were also compared with the values predicted by the UNIFAC model. For the quaternary system, an average rootmean-square deviation for the system in 75/25, 50/50, and 25/75 mass ratios as mixed solvents are(3.35, 5.21 and 5.65)%, respectively.
