Abstract
본 연구는 298.2K에서 acetone-ethanol, acetone-water, 그리고 ethanol-water 이성분계의 혼합엔탈피와 ace- tone-ethanol-water삼성분계의 혼합엔탈피를 실험에 의하여 측정하였다. 또한 Wilson식과 NRTL식을 이용하여 이성분계 혼합엔탈피 데이터로부터 얻은 매개변수를 이용하여 삼성분계 혼합엔탈피를 예측하였다. 본 실험에서 얻은 실험치와 각 모델로부터 예측된 추산치를 서로 비교하여 본 결과 2개의 매개변수를 갖은 용액모델로서 혼합엔탈피를 잘 예측할 수 있음을 알았다.
The enthalpies of mixing for the binary systems of acetone-ethanol, acetone-water and ethanol water and for the corresponding ternary liuid system of acetone-ethanol-water were measured at 298.2K. The ternary enthalpies of mixing were estimated from the results of tree binary systems by the wilson equation and the NRTL equation, and the predicted values were found to be in a good agreement with the experimental data.
