Abstract

In this work, the solid-liquid equilibria (SLE) of some aromatic organic mixtures including benzene, widely used as an industrial solvent, were measured by static method using our own made experimental apparatus. The accuracy and reproducibility of apparatus were tested by comparing experimental results with literature values for 1-dodecanol+cyclohxane and benzene + p-xylene systems. The SLE for new binary systems of benzene+aniline, benzene+nitrobenzene, p-xylene+cyclohexane were measured afterwards and compared with the calculated values by modified UNIFAC(Dortmund) equation.

본 실험에서는 대표적인 방향족 화합물이며 유기용매로 널리 이용됨에 따라 환경문제를 유발하는 벤젠을 포함한 방향족 유기혼합물에 대한 고액평형을 자체 제작한 장치로 정적방법에 의해 측정하였다. Benzene+p-xylene계화 1-dodecanol+cyclohexane계로서 실험방법의 정확성과 재현성을 확인하였으며, benzene+aniline, benzene+nitrobenzene, p-xylene+cyclohexane계의 새로운 고액평형데이터를 측정하고 수정된 UNIFAC(Dortmund)식에 의한 계산값과도 비교하였다.
